The effect of the composition of alumina/silicon carbide materials in an aluminochromophosphate bonding on the thermal expansion of the materials has been studied. The sharp increase in the relative lengthening of the experimental materials in the 160–250°C interval is associated with the polymorphous transformation of the cristobalite form of AlPO4. The thermal-expansion coefficient of

Is Silicon Carbide bonded through covalent network? | …

2009/2/11· Covalent network bonding is much stronger than covalent bonding, and seeing as how SiC''s melting point is 2000+ degrees Celsius, that''s the only thing that applies. It''s not ionic, because the bonding is between two nonmetals (metalloids like silicon don''t count as metals).
