Document Type and Number:
Japanese Patent JP2542402
Kind Code:
B2
Abstract:
A material resistant to high temperature melts of metal and salt which comprises a composite material containing silicon nitride, silicon oxynitride, silicon dioxide and silicon prepared by (a) suspending silicon powder in SiO2 sol to form a pourable mass, (b) molding a workpiece from said mass, (c) hardening the molded workpiece, and (d) nitriding the hardened workpiece in a nitrogen atmosphere to form silicon nitride and silicon oxynitride to a degree that SiO2 and elemental silicon remain detectable in the nitrided workpiece, is useful as the material of construction for crucibles and tools for confining, handling and treating melts of metals or salts.
