Title:
DEVICE CONSTITUTING MATERIAL FOR VAPOR PHASE CHEMICAL REACTION
Document Type and Number:
Japanese Patent JP3670479
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a reactor wall constituting material excellent in corrosion resistance, heat resistance, thermal impact resistance, durability of surface or the like, and usable for a high temp. vapor phase reacting device where a corrosive gas participates.
SOLUTION: This laminated structure is the one in which an inorganic formed body obtd. by bonding mullite and/or corumdum to alumina packing material and polycrystal alumina fibers in a uniformly mixed state is used as a base material, and it is provided with an intermediate layer composed of cloth made of ceramic fibers and an alumina-silica surface coating layer having 1.0 to 2.0 g/cm3 bulk density and 50 to 100 Vickers hardness.
