METHOD FOR PRODUCING FINE CRYSTAL PARTICLE TITANIUM SILICON CARBIDE CERAMIC

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a polycrystalline titanium silicon carbide ceramic having a small crystal particle diameter and a small particle diameter distribution which can be expected to improve low cutting machining precision and the occurrence of great chipping, which a conventional polycrystalline titanium silicon carbide ceramic having a large crystal particle diameter and a wide particle diameter distribution shows, and to provide the use thereof.;SOLUTION: The method for efficiently producing a polycrystalline titanium silicon carbide ceramic and products thereof having constitution of ≤15 μm the maximum crystal particle diameter defined by ≤6 μm of an average crystal particle diameter, ≤3 μm of a standard deviation and average+3×standard deviation, includes mixing silicon powder and titanium carbide powder with titanium hydride powder having ≤3 μm of an average crystal particle and ≤3 μm of a standard deviation of particle diameter and pressure-sintering the mixture powder.;COPYRIGHT: (C)2009,JPO&INPIT
