Publication number: US20220220354A1
Application number: 17/296,291

Abstract:
The present invention is a cured material of a thermal conductive silicone composition, the composition containing: 6 to 40 volume % of an organopolysiloxane as a component (A), and 60 to 94 volume % of a heat conductive filler as a component (B), the heat conductive filler containing; (B-i) unsintered crushed aluminum nitride having an average particle size of 40 μm or more and having 1 mass % or less of a fine powder with a particle size of 5 μm or less, and (B-ii) a heat conductive material other than the unsintered crushed aluminum nitride having an average particle size of 1 μm or more, where the component (B-ii) content is 30 to 65 volume %. This provides a cured material of a thermal conductive silicone composition excellent in handling properties and having a high thermal conductivity.

Application number: 17/299,051

Abstract:
The present invention is a method for manufacturing a gallium oxide film where a mist generated by atomizing a raw-material solution or by forming a raw-material solution into droplets is conveyed using a carrier gas, the mist is heated, and the mist is subjected to a thermal reaction on the substrate to form a film, where as the raw-material solution, a raw-material solution containing at least a chloride ion and a gallium ion is used, and the mist is heated for 0.002 seconds or more and 6 seconds or less. This provides a method for manufacturing an α-gallium oxide film at low cost with excellent film forming speed.

Application number: 17/620,373

Abstract:
A method for producing a vinyl chloride type polymer is to produce the vinyl chloride type polymer by polymerizing a vinyl chloride monomer, or a mixture of a vinyl chloride monomer with a monomer copolymerizable with the vinyl chloride monomer in an aqueous medium by using a polymerization reactor. An aqueous solution of a copolymerized polyether having a weight-average molecular weight of 1,000 to 3,500 with a mole ratio of ethylene oxide to propylene oxide in the range of 10/90 to 60/40 and having an alkyl group or an aryl group at both the terminals thereof is charged into the polymerization reactor with an amount of 0.005 to 0.050 parts by weight as the copolymerized polyether relative to 100 parts by weight of the vinyl chloride monomer.
