Tabular Alumina

Tabular alumina for sale is a pure sintered α-alumina material. It is also
known as white sintered alumina. Normally, the wholesale tabular alumina will
be fully densified by rapid sintering at temperatures exceeding 1900°C without
the use of sintering aids.

Tabular Alumina Properties
01.
Characteristic
HAOYUN wholesale china tabular alumina has characteristics of large, well-
developed hexagonal tablet-shaped α-alumina crystals of up to 200μm length.
02.
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.
03.
High Refractoriness
Tabular alumina for sale has extremely high refractoriness, high mechanical
strength and abrasion resistance, very good chemical purity, excellent
dielectric properties, and good resistance against acid and alkali corrosion.
04.
Aggregate of Choice
Sintered tabular alumina is the aggregate of choice in unshaped and shaped
high-performance refractory.
