    摘要: PURPOSE: To produce ultrafine metal nitride powder, by introducing and decomposing a specific metal compound and a carbon compound in hot steam, collecting produced mixed aerosol dispersoid, and heating the obtained carbon- containing mixture in a gaseous atmosphere containing nitrogen compound.
    CONSTITUTION: Air and fuel (e.g. propane) are introduced into the reaction furnace 1 through the duct 2 and the burner 3, respectively, and are burnt to fill furnace 1 with steam-containing hot-gas atmosphere of 600W2,000°C. A decomposable metal compound (e.g. TiCl
    4 ) and a decomposable carbon compound (e.g. xylene) are introduced through the nozzle 5 into the furnace 1, and are decomposed to obtain a mixed aerosol dispersoid containing the aerosol of metallic oxide and elemental carbon. The dispersoid is extracted through the duct 6 and cooled, and the obtained carbon-containing mixture is heated in a gaseous atmosphere containing a nitrogen compound (e.g. ammonia) at 700W2,500°C to effect the reduction reaction and the nitridation reaction and obtain the objective metal nitride.

    摘要: PURPOSE:To produce high-quality nonoxidizing material powder in low cost by feeding raw material powder to the inside of a furnace core pipe under the gaseous atmosphere from one end part of a horizontal type rotary furnace core pipe which is constituted of a carbon pipe and an oxidation-preventive protected pipe. CONSTITUTION:In case of producing ceramic powder of nonoxidizing material by using a synthesizing apparatus 1, raw material is introduced into a feed hopper 13 from an introduction port 12 and fed into the inside of a furnace core pipe 3 by a screw conveyor 15. Thereby raw material powder is moved to the right direction while rotating within the inside of a carbon pipe 8 under the gaseous atmosphere and passed through a reaction zone incorporated within a heating furnace 2. In case of the passing, since the outside peripheral wall of the furnace core pipe 3 is heated, raw material powder is allowed to react and thereby ceramic powder of nonoxidizing material is produced in the inside of the furnace core pipe 3. The product is taken out from a takeout hopper 17 via a takeout pipe 18 and the producing operation is finished.

    摘要: PURPOSE: To obtain flaky nitride ceramics with superior resistance to heat, thermal shock, corrosion, etc. by spraying a molten metallic or metalloid material on the surface of a cooling body, dropping the cooled thin chips before deposition, and nitriding them.
    CONSTITUTION: An element or a mixture of ≥2 kinds of elements selected from Si, Ti, B, Al, W, Zr, Hf, Nb, Ta, La, Fe, Co, Ni, V, Cr and Mo is melted and sprayed on the surface of a cooling body moving at high speed. The sprayed and cooled flaky material is dropped before it deposits on the surface of the cooling body. The flaky material is then nitrided by contact with a heated nitriding gas. By this method flaky nitride ceramics with superior heat resistance, strength, hardness, wear resistance, etc. is obtd. The average diameter of the ceramic is ≥10 times the thickness. The ceramics is suitable for use as a material for a machine, a structural material, etc.
