Abstract
A ceramic composition and method for making ceramic composites having superior erosion and corrosion resistance to molten metal. The composite includes mullite, aluminum nitride and boron nitride in combination. The composite may be hot pressed or cold formed and pressureless sintered into a desired shape.
Claims3
A ceramic composite which is corrosion and erosion resistant to molten metal comprising, in combination, 18.5 to 29.0 weight percent mullite, 35 to 18 weight percent aluminum nitride, balance boron nitride in a minimum concentration of at least about 40 percent by weight.
