摘要： PROBLEM TO BE SOLVED: To provide a novel iron oxide based powder excellent in acid resistance and heat resistance and capable of keeping 'specific surface area, the characteristics of iron oxide itself' even after high temp. heat treatment and the producing method. SOLUTION: The iron oxide based powder is formed by coexisting 5-25 wt.% silica in an amorphous state around the iron oxide powder and has a physical value of >=45 m2/g specific surface area after the heat treatment at 800 deg.C for 5 hr in the air. The powder is produced by using particularly 'silica sol using water as a dispersion medium' as the SiO2 raw material, neutralizing water soluble iron salt in an aq. solution, in which the silica sol is dispersed, to uniformly mix silica with iron oxide and depositing SiO2 around the iron oxide fine particle in a film state in a heating and firing step.

摘要： PROBLEM TO BE SOLVED: To obtain composite particles which are not poisoned and are excellent in production efficiency by coating the entire surfaces of core particles with coating layers so that the layers do not fall. SOLUTION: The composite particles are obtd. by forming coating layers of an inorg. material on the surfaces of core particles and the coating layers have rugged surfaces having 1-50 nm surface roughness. Coating layers of zirconia having 0.5-50 nm thickness or sulfur-free aluminous coating layers having 0.5-50 nm thickness are formed on the surfaces of the core particles.

摘要： PROBLEM TO BE SOLVED: To obtain a ceria.zirconia-base multiple oxide having a small average crystallite diameter and a large specific surface area and capable of maintaining its large specific surface area even after heat treatment as well as to increase oxygen storage ability by an increased degree of solid solution. SOLUTION: Ceria.zirconia solid soln. particles having >=50% degree of solid solution of Zr to Ce in a Ce-Zr solid soln. and a molar ratio Zr/(Ce+Zr) of 0.25-0.75 are mixed with oxide particles of a multiple oxide consisting of an alkaline earth metal oxide and zirconium oxide to obtain the objective multiple oxide. Since the oxide particles are allowed to coexist, the solid soln. phase is stabilized and the reduction of specific surface area at high temp. is suppressed.

摘要： PURPOSE:To obtain a silicon nitride-based sintered compact excellent in strength even at a high temp. of >=1,300 deg.C by specifying the amt. of oxygen in a sintered compact. formed by dispersing silicon carbide in a silicon nitride sintered compact. CONSTITUTION:When a silicon nitride-based sintered compact is composed of a silicon nitride sintered compact and silicon carbide grains dispersed in this sintered compact, value given by subtracting the amt. of oxygen capable of reacting with the metallic element of a sintering aid in the silicon nitride- based sintered compact from the total amt. of oxygen in the sintered compact is regulated to 0.5-6.9wt.% of the amt. of the entire sintered compact. By this regulation, the amt. of a glass phase forming grain boundaries is reduced and the amt. of silicon carbide grains incorporated into the glass phase is reduced. As a result, the area of contact, of the silicon nitride grains with the silicon carbide grains is increased, the silicon carbide grains easily prevent the lowering of the strength of the sintered compact due to the slippage of the silicon nitride grains at high temp. and the strength of the sintered compact at high temp. is enhanced.

摘要： PROBLEM TO BE SOLVED: To make compatible for both of oxidation inhibition of SO2 and oxidation acceleration of HC in a catalyst contg. a transition metal phosphate compound as a carrier. SOLUTION: This catalyst is composed of a composite carrier consisting essentially of a zirconium phosphate, a titanium phosphate and a noble metal deposited on the composite carrier. As oxidation of SO2 is inhibited with the zirconium phosphate, while the oxidation of HC is accelerated with the titanium phosphate by using both of the phosphates it is possible to compatibly inhibit both of the oxidation of SO2 and acceleration of the oxidation of HC.
