Description

Изобретение относится к составу прозрачного темно-красного стеклокристаллического материала, который может быть использован в стекольной промышленности, в частности в бытовой технике, в авиации, морском, железнодорожном транспорте и других отраслях промышленности. The invention relates to a composition of transparent dark red glass crystal material, which can be used in the glass industry, in particular in household appliances, in aviation, sea, rail transport and other industries.

Из всего разнообразия имеющихся стеклокристаллических материалов наибольшую значимость приобрела группа литиево-алюмосиликатных материалов, имеющих высокую прозрачность, низкое тепловое расширение, механическую прочность. Эти материалы имеют широкое и разнообразное применение лазерные оболочки, зеркала, жаростойкие пластины для кухонных плит, конструкционная оптика. Of all the variety of available glass-crystalline materials, the group of lithium-aluminosilicate materials having high transparency, low thermal expansion, and mechanical strength has gained the greatest importance. These materials have a wide and diverse application of laser shells, mirrors, heat-resistant plates for stoves, structural optics.

Известна окрашенная, прозрачная, полупрозрачная и непрозрачная стеклокерамика, включающая, мас. SiO2 63,5-69 Al2O3 15-25 Na2O 0,1-0,6 K2O 0,1-0,6 Li2O 2,5-4,0 ZnO 0-0,2 BaO 0-5 TiO2 2,5-6 ZrO2 0-2 As2O3 0,4-0,8 Fe2O3 0,05-0,2
Желаемый цвет получали, использовав в качестве красителей двух оксидов, выбранных из группы V2O5, CeO2, NiO, CaO, WO3, SnO2. Основной кристаллической фазой является твердый раствор β-кварца. Такая стеклокерамика используется в качестве обогреваемых окон.
Known painted, transparent, translucent and opaque glass ceramics, including, by weight. SiO 2 63.5-69 Al 2 O 3 15-25 Na 2 O 0.1-0.6 K 2 O 0.1-0.6 Li 2 O 2.5-4.0 ZnO 0-0.2 BaO 0-5 TiO 2 2.5-6 ZrO 2 0-2 As 2 O 3 0.4-0.8 Fe 2 O 3 0.05-0.2
The desired color was obtained using two oxides selected from the group V 2 O 5 , CeO 2 , NiO, CaO, WO 3 , SnO 2 as dyes. The main crystalline phase is a solid solution of β-quartz. Such glass ceramics are used as heated windows.

Судя по приведенному составу получить стеклокристаллический [1] материал с заданными свойствами не представляется возможным. Judging by the given composition, it is not possible to obtain a glass-crystalline [1] material with desired properties.

Наиболее близким к изобретению по технической сущности является прозрачная цветная стеклокерамика, включающая, мас. SiO2 62-68 Al2O3 19,5-22,5 Li2O 3,0-4,0 Na2O 0-1,0 K2O 0-0,1 BaO 1,5-3,5 CaO 0-1,0 MgO 0-0,5 ZnO 0,5-2,5 TiO2 1,5-5,0 ZrO2 0-3,0 MnO2 0-0,40 Fe2O3 0-0,20 CoO 0-0,30 NiO 0-0,30 V2O5 0-0,80 Cr2O3 0-0,20 F 0-0,20 Sb2O3 0-2,0 As2O3 0-2,0 ΣNa2O + K2O 0,5-1,5
ΣBaO + CaO 1,5-4,0 ΣTiO2 + ZrO2 3,5-5,5 ΣSb2O3 + As2O3 0,5-2,5
Исходное стекло варится при 1620оС [2]
Применение Cr2O3 в качестве красящего оксида сильно повышает верхнюю границу температуры расстекловывания. Введение V2O5 в комбинации с другими окрашивающими оксидами, такими как NiO, CoO, Fe2O3, с одной стороны, увеличивает пропускание в ИК-диапазоне, а, с другой, введение V2O3 в состав стекла, приводит к трудностям технологического характера. Ванадий образует несколько оксидов различной валентности, причем переход из одного состояния в другое происходит за счет небольшого смещения окислительно-восстановительного равновесия. Кроме того, V2O3 имеет негативное влияние на стабильность образования смешанных кристаллов h-кварца.
Closest to the invention in technical essence is transparent colored glass ceramics, including, by weight. SiO 2 62-68 Al 2 O 3 19.5-22.5 Li 2 O 3.0-4.0 Na 2 O 0-1.0 K 2 O 0-0.1 BaO 1.5-3.5 CaO 0-1.0 MgO 0-0.5 ZnO 0.5-2.5 TiO 2 1.5-5.0 ZrO 2 0-3.0 MnO 2 0-0.40 Fe 2 O 3 0-0 , 20 CoO 0-0.30 NiO 0-0.30 V 2 O 5 0-0.80 Cr 2 O 3 0-0.20 F 0-0.20 Sb 2 O 3 0-2.0 As 2 O 3 0-2.0 ΣNa 2 O + K 2 O 0.5-1.5
ΣBaO + CaO 1.5-4.0 ΣTiO 2 + ZrO 2 3.5-5.5 ΣSb 2 O 3 + As 2 O 3 0.5-2.5
The original glass is brewed at 1620 about [2]
The use of Cr 2 O 3 as a coloring oxide greatly increases the upper limit of the devitrification temperature. The introduction of V 2 O 5 in combination with other coloring oxides, such as NiO, CoO, Fe 2 O 3 , on the one hand, increases the transmittance in the infrared range, and, on the other hand, the introduction of V 2 O 3 in the glass composition leads to technological difficulties. Vanadium forms several oxides of different valencies, and the transition from one state to another occurs due to a small shift in the redox equilibrium. In addition, V 2 O 3 has a negative effect on the stability of the formation of mixed h-quartz crystals.

Целью изобретения является повышение светопропускания в видимой области. The aim of the invention is to increase the transmittance in the visible region.

Указанная цель достигается тем, что темно-красный прозрачный стеклокристаллический материал, включающий SiO2, Al2O3, Li2O, Na2O, K2O, BaO, TiO2, ZrO2, MnO2, CoO, NiO, As2O3, Sb2O3, согласно изобретению дополнительно содержит CdO при следующем соотношении компонентов, мас. SiO2 57 61,9 Al2O3 23 28 Li2O 4,5 5,5 Na2O 0,1 1,2 K2O 0,1 1,0 BaO 4,0 6,0 MnO2 0,1 0,5 TiO2 1,5 3,5 ZrO2 1,0 2,0 CdO 0,01 2,5 CoO 0,01 0,4 NiO 0,35 1,5 Sb2O3 0,1 1,0 As2O3 0,1 1,0
Дополнительное введение CdO в количестве 0,01-2,5 позволило достигнуть высокой прозрачности стеклокристаллического материала в видимой части спектра, так как в результате термообработки в стеклокристаллическом материале выделяются кристаллы β-кварцевых твердых растворов, размер которых 300-500

Figure 00000001
. Одновременное выделение таких кристаллов обеспечивает малые значения КТР в интервале температур 20-800оС и увеличивает термостойкость стеклокристаллического материала.This goal is achieved in that the dark red transparent glass crystal material, including SiO 2 , Al 2 O 3 , Li 2 O, Na 2 O, K 2 O, BaO, TiO 2 , ZrO 2 , MnO 2 , CoO, NiO, As 2 O 3 , Sb 2 O 3 , according to the invention additionally contains CdO in the following ratio of components, wt. SiO 2 57 61.9 Al 2 O 3 23 28 Li 2 O 4.5 5.5 Na 2 O 0.1 1.2 K 2 O 0.1 1.0 BaO 4.0 6.0 MnO 2 0, 1 0.5 TiO 2 1.5 3.5 ZrO 2 1.0 2.0 CdO 0.01 2.5 CoO 0.01 0.4 NiO 0.35 1.5 Sb 2 O 3 0.1 1, 0 As 2 O 3 0.1 1.0
An additional introduction of CdO in an amount of 0.01–2.5 made it possible to achieve high transparency of the glass-crystalline material in the visible part of the spectrum, since β-quartz solid solutions 300–500 crystals in size are released as a result of heat treatment in the glass-crystalline material
Figure 00000001
. Simultaneous isolation of such crystals provides small values of CTE over the temperature range 20-800 ° C and heat resistant glass-ceramic material increases.

Совместное присутствие NiO, MnO2, а также введение СоО в указанных соотношениях приводит к образованию красящего комплекса, обеспечивающего при вхождении в кристаллическую фазу селективного поглощения в требуемой области спектра.The combined presence of NiO, MnO 2 , as well as the introduction of CoO in these ratios, leads to the formation of a coloring complex, which ensures selective absorption in the desired spectral region upon entering the crystalline phase.

Снижение содержания SiO2 при одновременном повышении Al2O3 по сравнению с прототипом превышающих содержание щелочных оксидов способствует переходу части ионов алюминия в шестерную координацию, при этом резко понижается температура варки стекла и повышается термостойкость полученного материала.The decrease in the content of SiO 2 while increasing Al 2 O 3 compared with the prototype exceeding the content of alkaline oxides contributes to the transition of a part of the aluminum ions into gear coordination, while the temperature of glass melting sharply decreases and the heat resistance of the resulting material increases.

Увеличение содержания ВаО в сочетании с другими компонентами в составе стекла по сравнению с прототипом способствует увеличению области прозрачного стеклокристаллического материала с одновременным снижением температуры варки. The increase in the content of BaO in combination with other components in the glass composition compared to the prototype contributes to an increase in the area of transparent glass-crystalline material with a simultaneous decrease in the cooking temperature.

Конкретные составы стеклокристаллических материалов и их свойства приведены в табл.1 и 2. The specific compositions of glass crystal materials and their properties are given in tables 1 and 2.
