High Purity Alumina Refractory Corundum Mullite Crucible

■ Introduction：

The High Purity Alumina Refractory Corundum Mullite Crucible is applying the the electro-fused white corundum and electro-fused mullite as the main raw materials. The main processing procedures are material mixing, granulation, pressing molding, drying and dehydration, and high temperature sintering. The High Purity Alumina Refractory Corundum Mullite Crucible has the advantages of high temperature resistance, high hardness, oxidation and corrosion resistance etc. The High Purity Alumina Refractory Corundum Mullite Crucible are widely used in the sintering of special ceramics, electronic ceramics, phosphors, rare earth and other materials.

■ Technical data sheet:

■ Advantages:

(1) Corundum mullite crucible has enough mechanical strength at room temperature, the corundum mullite crucible will not be damaged when carrying and loading the load.

(2) High purity alumina mullite crucible has very high soften temperature, which 50-100 ℃ higher than that of the product firing temperature, so as to ensure that the crucible will not soften and deform at the firing temperature of the product.

(3)Refractory Corundum mullite crucible has very high refractory temperature, which is over 300℃ higher than that of the products firing temperature .

(4) Refractory High purity alumina crucible has excellent thermal shock resistance, The corundum mullite crucible will keep certain mechanical strength and will not be broken after repeated heating and cooling.

(5) The High Purity Alumina Refractory Corundum Mullite Crucible has good thermal conductivity and certain gas permeability, so as to ensure that the heat and atmosphere of the combustion product can be quickly transmitted to the product.
