Low Sodium tabular aluminum oxide low price

Tabular Aluminum Oxide is a purely sintered α-corundum material that is a compact body rapidly sintered at temperatures above 1900 ° C without sintering aids. Tabular aluminum oxide has approximately 200 μm and well-developed hexagonal plate-like α-corundum crystals. Its excellent thermal volume stability and thermal shock resistance can be attributed to the following special microstructure of platy corundum: less open pores, large crystals, closed spherical pores due to recrystallization trap during rapid sintering.
Tabular Aluminum Oxide has high heat resistance, mechanical strength, abrasion resistance, high chemical purity, excellent insulation properties, acid and alkali corrosion resistance.
Tabular Aluminum Oxide is the preferred aggregate of amorphous and shaped high performance refractory materials, widely used in steel, casting, petrochemical, ceramics and incineration industries as well as electrical insulation, kiln furniture and catalyst carriers. Finely ground tabular aluminum oxide powder is an excellent product that used as a filler in epoxy resins or resin systems. It is used to obtain the desired high dielectric strength, thermal conductivity and wear resistance.
