Mullite alumina ceramic crucible
Mullite alumina ceramic crucibles, crafted from mullite, are indispensable tools primarily utilized in the sintering of electronic and magnetic materials. These materials, during the sintering process, often undergo chemical reactions with the ceramic crucible's surface. To address this, our company meticulously selects materials for the saggers used in sintering various magnetic materials. These saggers are formed under high pressure and subsequently sintered at high temperatures, ensuring their robustness and efficacy.
Crucibles for melting steel features:
1) High density
2) Good thermal stability and distortion resistance at high temperature.
3) High mechanical strength at high temperature.
4) Excellent thermal shock resistance.
5) High thermal conductivity.
6) Perfect oxidating resistance.
7) Excellent corrosion resistance against chemicals at high temperature.
8) High abrasion resistance.
9) Long service life
