  • Publication number: 20210032415
    Abstract: Provided is a method for producing cellulose particles or cellulose acetate particles. By a production method including: (a) dissolving cellulose acetate in an organic solvent and preparing a cellulose acetate solution; (b) obtaining an emulsion of the cellulose acetate solution and an aqueous medium using a porous membrane; and (c) precipitating cellulose acetate particles from the emulsion, cellulose acetate particles are produced. By further saponifying the cellulose acetate obtained by the production method, cellulose particles are produced.

  • Patent number: 10273191
    Abstract: Provided is a zirconia sintered body having both high translucency and high strength. The zirconia sintered body includes crystal grains that include a cubic domain and a tetragonal domain, wherein a stabilizer and lanthanum is dissolved as a solid solution therein. The sintered body can be obtained by a manufacturing method including: a mixing step of obtaining a mixed powder by mixing a zirconia source, a stabilizer source, and a lanthanum source; a molding step of obtaining a green body by molding the obtained mixed powder; a sintering step of obtaining a sintered body by sintering the obtained green body at a sintering temperature of 1650° C. or higher; and a temperature lowering step of lowering the temperature from the sintering temperature to 1000° C. at a temperature lowering rate exceeding 1° C./min.
