Alumina Ceramics Description. Alumina, or aluminum oxide Al2O3, with a molecular weight of 102, is the major source of aluminium in nature. Al2O3 has very high melting point, which is 2,072 °C and it is extremely hard. Alumina ceramic is the most common technical ceramic material and relatively traditional material.
It is a very good abrasive resistant and has high refractoriness. The R.U.L. ( Refractoriness Under Load ) of High Alumina Brick 60% AL 2 O 3 is 1420 °C. Its A.P. ( Apparent Porosity ) is 23%,.
