Classification of composite materials
Such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, uranium oxide, Magnesium Oxide, cerium and thorium oxide melting point at 2050~3050 DEG C.
Refractory compound material
Such as carbide (silicon carbide, titanium carbide, tantalum carbide, etc.) nitride (boron nitride, silicon nitride, boride etc.) (zirconium diboride, titanium diboride, Hafnium silicide, etc.) (two molybdenum silicide etc.) and sulfide (thorium and cerium sulfide etc.). They have a melting point of 2000~3887, of which carbides are the most difficult to melt.
High temperature composite material
Such as cermet, high temperature inorganic coating and fiber reinforced ceramics.
