APPLICATION
Widely used in non-ferrous metallurgy, building materials, petrochemicals, large power plant boilers, incinerators, and other fields. Can also be used as melt spray coating, with a high temperature plasma gas sprayed directly to metal, ceramic and other surfaces, giving the latter a very high wear resistance, corrosion resistance and high temperature resistance. Can also mixed chrome green oxide and alumina or zirconia fused, produced high performance refractory materials.
