  • Patent number: 9796598
    Abstract: A method for producing a potassium titanate easily and inexpensively produces a potassium titanate that exhibits high thermal stability and has a significantly low fibrous potassium titanate content. The method for producing a potassium titanate includes calcining a raw material mixture by heating the raw material mixture to a maximum calcination temperature that exceeds 1000° C. while controlling the heating rate from 1000° C. to the maximum calcination temperature to 15° C./min or less to obtain a calcine, and cooling the calcine while controlling the cooling rate from the maximum calcination temperature to 500° C. to 100° C.

  • Patent number: 9598320
    Abstract: Provided is a method of producing a composite metal oxide including, to calcine a composition containing an alkali metal and obtain a composite metal oxide, calcining the composition while being arranged on a mount a part of which in contact with the composition is formed of a metal oxide component. The metal oxide component has a content of K atoms ranging from 5 to 13 parts by weight in terms of K2O with respect to 100 parts by weight of the metal oxide component, and a total content of Al atoms, Zr atoms, Mg atoms, and Ce atoms ranging from 15 to 70 parts by weight in terms of oxides with respect to 100 parts by weight of the metal oxide component. The present invention thus provides a method of producing a composite metal oxide containing an alkali metal with reduced production costs.
