3.50 G / Cm3 Min Density Tabular Alumina , Refractory Alpha Aluminum Oxide
Tabular Alumina
1 . Product Description
Tabular alumina is produced by sintering ball-formed, intermediately burned calcined alumina at a temperature just under the 2040º C melting point of aluminum oxide.
These tabular alumina balls are then crushed, graded or screened, ground and blended to a wide range of granular or powdered particle size distributions.
