Alumina Ceramic Long Lifespan Refractory Wear Resistant High Temperature Ceramic Bowl
Under the general condition, the analyzed and fired substance is
put into the alumina crucible or a bowl and then put into analyzing
or firing equipment to be heated. Heating and cooling speed is different according to the
characteristics of the equipment and products. A raw material for manufacturing the alumina crucible and the bowl is subjected to thermal expansion, and the alumina crucible and the
sagger are easily cracked if the heating or cooling speed is
overhigh, so that the speed had better be low to prolong the
service life of the crucible and the bowl.
Features:
1. Good thermal conductivity
2. Good high temperature strength
3. Wear resistant and erosion resistant
4. Good thermal shock resistance
5. Good corrosion resistance
6. Good oxidation resistance
7. Not easy in deformation and cracking
