Background technology
Development rapidly since nineteen ninety-five, transparent ceramic laser material obtained Laser output.The report that Nd:YAG crystalline ceramics composite construction is arranged again in recent years, this material only are that the concentration of Nd ion in the YAG transparent ceramic material is different, so sintering temperature is consistent.The crystalline ceramics functionally gradient material (FGM) of the wish preparation that proposes with the present invention has larger difference, the crystalline ceramics functionally gradient material (FGM) that the present invention proposes, and in this material, doping ion concentration and matrix material constituents all change.Because this variation causes the sintering temperature of material variant, this material preparation has higher difficulty and novelty.This material preparation awaits the innovation of agglomerating plant.
Yet there are no at present report both at home and abroad about the crystalline ceramics functionally gradient material (FGM).
The crystalline ceramics functionally gradient material (FGM) is in preparation, and the sintering temperature of raw material has great difference, and the sintering characteristic of various raw materials is different, uses single sintering temperature and can not obtain well behaved sintered body.Address this problem, the part that sintering temperature is higher should be burnt till under higher temperature, the lower raw material of sintering temperature should burn till under lower temperature simultaneously, namely realize sintering under default temperature, the approach that obtains this thermograde is the zone sintering stove that preparation has suitable sintering temperature.
For this requirement, special proposition the present invention.
Summary of the invention
The effect of sintering furnace of the present invention is the functionally gradient material (FGM) that required powder is molded on request definite shape, under vacuum or hydrogen atmosphere, under certain material feed speed, control furnace program, realize the coupling of furnace body temperature-material sintering temperature, sintering is prepared into the crystalline ceramics functionally gradient material (FGM).
Technical solution of the present invention is as follows:
A kind of temperature control-material feeding coupled zone fritting furnace is characterized in that mainly comprising: vacuum system, in order to produce the required vacuum of preparation crystalline ceramics; The hydrogen gas flow controller is in order to produce the required hydrogen atmosphere of preparation crystalline ceramics; Heating system, effect are to produce required temperature by PID control; Cooling system, effect are to take away the unnecessary heat that heating system produces, and also can produce certain temperature field simultaneously; Material feed system, effect are by control system, and control material feed speed realizes the coupling of furnace body temperature-material sintering temperature; Control system, effect are that control temperature, material feeding, atmosphere are moved under the condition that requires.
Described furnace construction schematic diagram is seen Fig. 1.Mainly comprise:
(1) vacuum system is carried out forvacuum to body of heater;
(2) hydrogen gas flow controller is in order to produce the required hydrogen atmosphere of preparation crystalline ceramics;
