Zirconia ceramic sintering adopts recrystallized silicon carbide setter plate

The sintering temperature of zirconia ceramics is very high when the recrystallized silicon carbide setter is used for production. high;

The working temperature of the recrystallized silicon carbide setter plate can reach 1650 ℃; the thermal shock resistance is excellent and the best setter plate; but because the main component of the silicon carbide setter plate is SIC+SIO2;

Among them, the SIO2 in the recrystallized silicon carbide setter plate cannot be completely obtained from the group, so some SIO2 still exists in the form of crystalline;

Due to the relatively high activity of SIO2, when SIO2 encounters all substances that can be combined at high temperature, it will immediately combine reaction or pollute the burning product;

Therefore, the zirconia ceramics will still be polluted when the recrystallized silicon carbide setter is selected;
