Study on the alumina - silicon carbide - carbon based trough …

Calcined alumina is an aluminum oxide that has been heated to temperatures in excess of 1050°C (1900° F) to remove chemically coined water. In this form, alumina has great chemical purity, high density, extreme hardness (9 on the Mohs hardness scale), and a high melting point (slightly above 2,050° C [3,700° F]).

Physico-chemical characterisation of silicon carbide …

1/1/2006· Silicon carbide-based refractories have been chemically characterised by different methods. The best method for each particular refractory depends on the crystalline phases (silicon carbide and others) present in the sample, as well as the average size of the SiC particles (refractories containing small SiC particles cannot be analysed by the wet method because silicon is easily oxidised).
