Abstract:
A refractory metal matrix-ceramic compound multi-component composite material with the super-high melting point is disclosed. At least one ceramic compound A and at least one refractory bonding metal B are fused together by the smelting process to make the multi-component composite material. The fused ingredients of the multi-component composite material are mAnB, and 2≤(m+n)≤13. The positive integer m is the number of the kinds of the ceramic components A, and the positive integer n is the number of the kinds of the refractory bonding metals B. The absolute value of the combining enthalpy of the ceramic compound A is larger than the absolute value of the combining enthalpy between the ceramic compound A and the refractory bonding metal B. The material has the properties including over 3000° C. melting point, high stability, hardness, ductility, and fusibility in high or low temperature, fast production, and low cost.
