Yixing Kam Tai High temperature Cordierite Refractory Crucible for glass industry
1. Description
Our Cordierite refractory crucible is widely used to sinter powder and glass, like rare earth powder, phosphor, pigment, sponge iron and so on. When these powder sintered in kiln, powder itself has water ,it has bad effect to sagger's using life. So it must has high thermal shock resistance when sintering.
Cordierite makes the ceramic manufacture of products like catalytic converters possible. They constantly heat up and cool down quickly and must not crack because of the shock. These converters get their thermal shock resistance properties from a bonded matrix of low-expansion cordierite crystals. These crystals form during firing between 1300 to 1400C (interestingly, cordierite crystals have a lesser thermal expansion along one axis than another). Thus, the better the density of the precursor mix and controlled the firing the better the properties of the cordierite material are.
