Description
Изобретение относитс к области порошковой металлургии и может быть использовано дл изготовлени футеровочных плит дл металлургических печей, химических аппаратов и фасонных изделий, примен ющихс в качестве огнеупорных и электроизол ционных деталей в различных устройствах новой техники.The invention relates to the field of powder metallurgy and can be used for the manufacture of lining plates for metallurgical furnaces, chemical apparatuses and shaped articles used as refractory and electrical insulating parts in various devices of the new technique.
Известеи огнеупорный материал, включающий нитрид бора п карбид кремни .Lime refractory material including boron nitride p silicon carbide.
Цель изобретени - повысить химическую устойчивость и обеспечить стабильность физико-химических характеристик.The purpose of the invention is to improve chemical resistance and ensure the stability of physicochemical characteristics.
Достигаетс это тем, что огнеупорный материал содержит нитрид бора 2-70 вес. %, кадбид кремни 10-49 вес. % и, кроме того, карбид бора 20-49 вес. %.This is achieved by the fact that the refractory material contains boron nitride 2-70 weight. %, silicon cadbide 10-49 weight. % and, in addition, boron carbide 20-49 weight. %
Издели из огнеупорного материала получают следующим образом.Products made of refractory material is obtained as follows.
Порошки исходных компонентов смешивают в необходимом соотношении в шаровой мельнице в течение 18 час, после выгрузки из мельницы смесь замешивают на пластификаторе-растворе синтетического каучука в бензине . Затем производ т прессование заготовок и спекание их в печи сопротивлени с графитовым нагревателем при температуре 2050-2100°С в засыпке из питрида бора в токе азота в течение 1 час.The powders of the initial components are mixed in the required ratio in a ball mill for 18 hours, after unloading from the mill, the mixture is kneaded on a plasticizer-solution of synthetic rubber in gasoline. Then, the blanks are pressed and sintering them in a resistance furnace with a graphite heater at a temperature of 2050-2100 ° C in boron pyridium bed in a stream of nitrogen for 1 hour.
Полученный материал обладает следующими свойствами:The resulting material has the following properties:
