The effect of Sintering Temperature in High Temperature Vacuum Sintering Furnace on SiC-YAG Ceramic Composites
In order to study the effect of high-temperature vacuum sintering furnace on sintering temperature in mass loss, under the experimental conditions of holding time of 30min and aluminum button molar ratio of 1.67, the SiGYAG ceramic composite materials prepared by mechanical mixing method were studied in different high-temperature vacuum sintering. Weight loss rate at furnace sintering temperature.
The weight loss rate of the SiCYAG ceramic composite material prepared by the mechanical mixing method varies with the sintering temperature of the high-temperature vacuum sintering furnace. It can be seen that as the sintering temperature of the high-temperature vacuum sintering furnace increases, the weight loss rate of the SiG YAG ceramic composite material prepared by the mechanical mixing method gradually increases, that is, with the increase of the sintering temperature of the high-temperature vacuum sintering furnace, the SiC-YAG ceramic composite material Serious loss of quality. From 1800°C to 1950°C, the weight loss rate of SiG-YAG ceramic composite material increases greatly, and after 1950°C, the weight loss rate of SiC-YAG ceramic composite material hardly changes, which shows that SiC-YAG ceramic composite material In the high-temperature vacuum sintering furnace sintering process, quality loss does occur.
When the sintering temperature of the high-temperature vacuum sintering furnace exceeds 1950 degrees: in the future, these low melting point products are almost volatilized, so the weight loss rate of the SiC-YAG ceramic composite material hardly changes. This result can be inferred that the SiC-YAG ceramic composite material undergoes a chemical reaction during the sintering process in a high-temperature vacuum sintering furnace, resulting in low melting point and volatile substances, resulting in quality loss.
