MANUFACTURING PROCESS FOR REFRACTORY MATERIAL, PROTECTIVE COATING OBTAINED BY THE PROCESS, USE OF THE PROCESS AND USE OF THE COATING

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing process for a refractory material minimum in the quantity of free carbon or free silicon and having remarkable oxygen barrier characteristics even at a very high temperature. SOLUTION: The manufacturing process for the refractory material is performed by (a) depositing a 1st dispersion body containing a powdery metallic compound composed of a borate of a transition metal and a resin containing≥30% carbon component after carbonization on the surface of a base material or in a mold, (b) drying the resultant deposit, (c) crosslinking the resin existing in the deposit, (d) carbonizing the resin in an inert atmosphere, (e) covering with a 2nd dispersion body containing powdery silicon and a binder and (f) heating a material obtained in the step (e) to a temperature equal to or above the melting point of silicon in the inert atmosphere.
