    Abstract: The present invention involves a process and system for producing spherical BNxOy particles that are converted to crystalline BN. The process involves adding a boron compound to an aqueous solution, creating an aerosol spray from the solution in the form of aerosol droplets using an aerosol generator. The aerosol droplets are fed with an inert carrier gas into a heated furnace at a preset flow rate while simultaneously injecting a gaseous nitriding agent into the heated furnace in a direct proportion to the flow rate of the carrier gas containing the aerosol droplets whereby a precursor of spherically shaped BNxOy particles are formed which are further heat treated into particles of spherically shaped BN having a turbostratic or hexagonal structure.

    Abstract: The present invention provides the amorphous silica particles having a double structure of a core of the dense amorphous silica and a shell of the bulky amorphous silica, having a volume-based median diameter of from 1 to 5 &mgr;m and containing not more than 10% by volume of fine particles having a particle diameter of not larger than 0.5 &mgr;m. The amorphous silica particles of the double structure have constant particle diameters not only in the powdery state but also in a state where they are blended in a coating material or in a resin, without developing fine particles, exhibit excellent delustering action and antiblocking action, exhibit decreased abrading property, and exhibit excellent resistance against scars or abrasion.

    Abstract: A solid acid-base catalyst contains vanadium pentoxide hydrate. Moreover, it is preferable that the vanadium pentoxide hydrate in the solid acid-base catalyst has a composition which is represented by the following general equation (1):V2O5.nH2Onullnull(1)(n: 0.1-3). Creation of the vanadium pentoxide hydrate was confirmed by measuring X-ray diffraction spectrum shown in FIG. 1. In accordance with the above arrangement, the solid acid-base catalyst can sufficiently display catalytic activity under mild conditions, and it can be suitably applied to various reactions, such as the syntheses of olefins or ethers through dehydration reactions of alcohols, the syntheses of aldehydes or ketones through dehydrogenation reactions of alcohols, hydrations and isomerization reactions of olefins, alkylations, esterifications, amidations, acetalizations, aminations, hydrogen shift reactions, aldol condensation reactions and polymerization reactions.

    Abstract: A surface-fluorinated metal oxide particulate comprising a metal oxide particulate selected from titanium, aluminum, silicon, silver, copper, zirconium, zinc, tin, germanium, tantalum and the like, being reacted with fluorine and a process for manufacturing such surface-treated metal oxide particulates are disclosed. The process allows easy and efficient fluorination of the surface of metal oxide particulates in any desired ratio. The surface-fluorinated metal oxide particulates of the present invention are useful as an additive for weatherable paints, weatherable resins, cosmetics and the like. Surface-fluorinated titanium oxide particulates obtained by fluorination of titanium oxide particulates have improved light stability, water-repellence, and dispersibility as compared with conventional titanium oxide particulates and maintains surface smoothness of the resin-coated substrate when contained in high concentrations in thermoplastic resins as a white pigment with water content being controlled in a specified range and prevents the occurrence of troubles at the time of melt extrusion coating for obtaining resin-coated substrates.
