Title:
CARBON-CONTAINING REFRACTORY
Document Type and Number:
Japanese Patent JP2529501
Kind Code:
B2
Abstract:
PURPOSE: To provide a carbon-containing refractory capable of holding its high strength in a wide temperature range and reduced in the lowering of the strength even under an oxidative atmosphere condition.
CONSTITUTION: The refractory comprises 100 pts.wt. of a fire-resistant aggregate comprising 50-97wt.% of a mixture of one kind or more of fire-resistant oxides, nitrides, borides and carbides and 3-50wt.% of a carbon material, 0.3-10 pts.wt. of boron carbide, and 0.3-15 pts.wt. of a mesophase pitch containing an optically anisotropic mesophase pitch in an amount of ≥60% and giving a carbonization yield of ≥70%, and the refractory can, if necessary, further contain 0.5-5 pts.wt. of a thermosetting resin.
