Title:
INORGANIC FIBER SINTERED COMPACT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2579854
Kind Code:
B2
Abstract:
PURPOSE: To obtain a sintered compact having high strength and toughness by constructing an inorganic fiber sintered compact from inorganic fiber composed of Si-Ti-C-O and an inorganic substance, present in the interface of the fiber and composed of Si-Ti-O.
CONSTITUTION: Inorganic fiber is constructed from an amorphous substance substantially composed of Si and M (Ti or Zr) or an assembly substantially composed of β-SiC, MC and solid solution of the β-SiC and MC and/or crystal grains of MC1-X (X is a number of ≥0 and <1) and amorphous SiO2 and MO2. The amorphous substance substantially composed of the Si, M and O or a crystal assembly composed of crystalline SiO2 and MO2 is present in the interface of the inorganic fiber and the resultant substance is then sintered by heating at a temperature within the range of 1400-1900°C to form a surface layer. Thereby, the objective inorganic fiber sintered compact having a high strength and toughness is obtained.
