Corundum Mullite Calcining Crucible

Corundum Mullite Calcining Crucible:c

With an extreme high percentage of alumina content, corundum mullite calcining crucible boosts high purity, high thermal resistance with little slag stripping. It is widely used in powder calcining especially in laboratories in the universities or some institutes for precious non-ferrous metal powder calcination.

Raw Materials:

Fused or sintered granule as the aggregate and synthesized corundum powder as the powder material

With aluminum oxide of high purity and fused corundum or sintered corundum as the raw materials, we use casting or high pressure molding method to produce high quality and high purity aluminium oxide with good thermal, mechanical and chemical performance.

Qualities:

I. Good errosion-resistance but relatively poor thermal shock resistance

II. With high purity and high stability, the refractory crucible won’t react with the sintered product with little slag stripping

III. Through high pressure and high temperature, the mullite and corundum crystal can be effectively combined, constructing the aggregate of more stable with good thermal shock resistance and compression ability, thus a longer working life.

Other features:

l compact structure

l high compressive strength

l acid and alkali corrosion resistance

l anti stripping, anti pulverization and long service life

l widely used in the smelting of rare earth magnetic materials, alloy materials and sintering of ceramic powders

Application：

The refractory box can be used to contain refined ceramics, magnetic materials, rare earth, fluorescent powder, etc.
