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./min or more, followed by grinding, the raw material mixture including a titanium compound and a potassium compound so that the molar ratio (number of moles of titanium compound on a titanium atom basis/number of moles of potassium compound on a potassium atom basis) of the number of moles of the titanium compound on a titanium atom basis to the number of moles of the potassium compound on a potassium atom basis is 2.7 to 3.3.
