Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an approximately nano-degree thermal decomposition method oxide having a minimal chloride content and a BET surface area of 1-600 m
2 /g without necessitating an extremely high vaporization temperature.
SOLUTION: This oxide is obtained by dissolving an organic metal material in a solvent and converting it into an oxide in a flame at a temperature over 200°C.

Abstract: PROBLEM TO BE SOLVED: To provide nano size oxide with a slight amount of chloride and BET specific surface area of 1-600 m2/g through a thermo-decomposition method which does not need an extremely high evaporation temperature. SOLUTION: In manufacturing through a thermo-decomposition of metal and/or metalloid, oxide and/or mixed oxide in nano size is controlled to become 1-600 m2/g in BET specific surface area and less than 0.05 mass % in total chloride content.

Abstract: PROBLEM TO BE SOLVED: To produce a nanoscale yttrium-zirconium compound oxide by thermal decomposition which is characterized in the that the intrinsic tetragonal crystal system is maintained without transformation to the monoclinic system even after being stored for one month. SOLUTION: The nanoscale yttrium-zirconium compound oxide is produced by spraying an yttrium compound and a zirconium compound or a solution or a suspension obtained by dissolving or dispersing these compounds in a solvent, and then converting these compound into the yttrium-zirconium compound oxide at a temperature higher than 200 deg.C in a flame, preferably an detonating gas.

Abstract: PROBLEM TO BE SOLVED: To product a silicic acid modified to silane and reducing viscosity. SOLUTION: Water or a dilute acid is first sprayed on silicic acid in a proper mixing vessel if necessary and then a surface modifying reactive agent or a mixture of several kinds of surface modifying reactive agents is sprayed. They are stirred for 15-30min, heat-treated at 100-400 deg.C for 1-6r, broken, compressed and pulverized to produce the objective silicic acid modified to silane and having such physical and chemical characteristics as 80-400m /g specific surface area, 7-40nm primary particle size, 50-300g/l tap density, pH3-10, 0.1-15% carbon content and

Abstract: PROBLEM TO BE SOLVED: To obtain hydrophobized oxides having a markedly low content of acidic by-products by hydrophobizing pyrolytically obtained metal and/or metalloid oxides, oxide mixture or mixed oxide with a hydrophobizing agent so that the formed oxide may contain dimethylsilyl groups and monomethylsilyl groups in a specified ratio. SOLUTION: Subsequently to the production, an acidic oxide, (e.g. Aerosil) is mixed with a hydrophobizing agent previously vaporized in an evaporator 1 in a conduit 2, and together with steam generated in an evaporator 4 is continuously treated in a fluidized bed 1. The hydrophobization temperature is about 20 to about 800 deg.C, advantageously, about 400 to about 600 deg.C. The hydrophobizing agent used is a halogen-free acyclic siloxane, a monocyclic methylcyclosiloxane mixture D3-D9, advantageously, octamethylcyclotetrasiloxane D4. The hydrophobization temperature is controlled so that the ratio of dimethylsilyl groups to monomethylsilyl groups may fall within the range of 100/0 to 50/50. The adherent acid and excessive hydrophobizing agent are removed in a countercurrent fluidized bed 2.
