The method that low cost easily manufactures potassium titanate is provided, the potassium titanate has high heat endurance and significantly reduced fibrous material content.A kind of manufacture method of potassium titanate, it is characterised in that：Heat and calcine the raw mixture comprising titanium compound and potassium compound so that be less than 15 DEG C/minute from 1000 DEG C to the programming rate of highest calcining heat when raw mixture is warming up to the highest calcining heat more than 1000 DEG C；Cool down products therefrom afterwards so that from highest calcining heat to 500 DEG C of cooling rate be more than 100 DEG C/minute；And crush thus obtained cooling thing, the mol ratio represented wherein in raw mixture by (molal quantity of the titanium compound of titanium atom conversion)/(molal quantity of the potassium compound of potassium atom conversion) is 2.7 3.3.
