Abstract
The object of the present invention is to provide free-machining machineable ceramic which is excellent in free-machining property and various physical property values and which is sintered at a temperature of 1550° C. or less without a liquid phase. It is produced by sintering at a temperature of 1450-1550° C. at a composition ratio of 10-75 vol % of ZrSiO4, 15-50 vol % of h-BN, and 10-50 vol % of ZrO2. More preferably 10-60 vol % of ZrSiO4, 20-50 vol % of h-BN, and 21-50 vol % of ZrO2.
