Tabular Alumina Properties

Characteristic

HAOYUN wholesale tabular alumina has characteristics of large, well-developed hexagonal tablet-shaped α-alumina crystals of up to 200μm length.

Specific Microstructure

The excellent thermal volume stability and thermal shock characteristics can be attributed to the specific microstructure of tabular alumina: low open porosity and large crystals with closed spherical pores, which are entrapped upon re-crystallization during rapid-sintering.

High Refractoriness

Tabular alumina for salehas extremely high refractoriness, high mechanical strength and abrasion resistance, very good chemical purity, excellent dielectric properties, and good resistance against acid and alkali corrosion.

Aggregate of Choice

Tabular alumina is the aggregate of choice in unshaped and shaped high-performance refractory.

There are many abrasive material suppliers, but we are one of the best choices for you.
