摘要： Spherical silica powder is produced by feeding silica powder having an average particle size of 0.3-40 &mgr;m to a burner flame formed with a flammable gas so as to continuously melt and spheroidize the particles within the flame. The use of a non-halogenated siloxane and/or alkoxysilane as an auxiliary flame-generating source raises the flame temperature and increases the length of the composite flame formed by combustion of the fuel gas with the siloxane or alkoxysilane. Moreover, the fine particles of silica that form as a result of siloxane or alkoxysilane combustion unite and coalesce with the particles of starting silica. These effects accelerate melting and spheroidization of the starting silica powder, resulting in thermally efficient and cost-effective spherical silica powder production.

摘要： In a first step, a crosslinkable organopolysiloxane oil (2) is mixed with an inorganic filler (3) in a flow jet mixer (1) to form a flowing silicone rubber compound. In a second step, the silicone rubber compound is fed into a tank (6) equipped at the bottom with a vacuum discharge pump (8) and maintained in vacuum where the compound is continuously deaerated, and a thixotropy controlling agent (10) is then added and mixed with the compound in a mixer (9). In a third step, a crosslinking agent (12) is added and mixed with the silicone rubber compound in a KRC kneader (11), and the compound is degassed in a mixer (13). The process continuously produces an RTV silicone rubber composition which is anti-sagging and improved in applicability on use.

摘要： In a fluidized bed reactor for preparing a metal nitride by feeding metal powder and a non-oxidizing gas containing N.sub.2 or NH.sub.3 into a reaction tube (1) to form a fluidized bed (2) therein and heating the fluidized bed for nitriding the metal powder, an envelope (11) encloses the reaction tube (1) for preventing the surrounding air from entering the reaction tube. A heater (9) is disposed outside the envelope (11) for heating the fluidized bed (2) to 1,200.degree. C. or higher. The envelope prevents penetration of the surrounding air into the reaction tube and also prevents deterioration of the heater and surrounding components by scattering of metal fines. The reactor ensures safe operation to prepare metal nitride powder of high purity on an industrial scale.
