REFRACTORY USING REFRACTORY RAW MATERIAL COATED WITH NANOCARBON

摘要

PROBLEM TO BE SOLVED: To improve especially the hot strength in a refractory using a refractory raw material coated with nanocarbon.

SOLUTION: The refractory is produced by adding an organic resin to a refractory raw material mixture containing a refractory raw material coated with nanocarbon in which at least a part of the surface of a refractory raw material particle is coated with carbon nanofibers and/or carbon nanotubes and kneading, and heat-treating the obtained body after molding, where the refractory raw material coated with nanocarbon having an amount of residual carbon obtained from the organic resin which is 1.2 mass% or more and 10.0 mass% or less to the mass of the whole refractory raw material mixture is used for the refractory.
