hard strong Zirconia Ceramic sealing raschig joint ring
Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
The usual firing temperature does not allow the two materials to be sufficiently effectively combined, so it is necessary to add an appropriate amount of αΑL2O3 to form the two particles. SIO2 in high-quality corundum mullite bearing board is non-free state; it has been combined with AL2O3 to form mullite crystal; the thermal expansion coefficient of mullite and low (≈0.08), mullite phase transformation temperature is Above 1800 °C; corundum mullite bearing board will not change or soften when used at 1650 °C; therefore, the thermal shock resistance of the bearing plate produced by using appropriate amount of fused mullite and alumina corundum Well, the use temperature is above 1650 ° C; sintering of Zirconia Ceramics using corundum mullite bearing board is a preferred preferred setter; the excellent corundum mullite bearing board can not have the presence of glass phase On the contrary, the existence of a glass phase in the corundum mullite bearing plate cannot be used to sinter the zirconia ceramic, and there is a pollution reaction phenomenon in the presence of the free silicon bearing plate.
