ABSTRACT:
A method of manufacturing readily machinable high strength glass ceramics includes the steps of: preparing a powder mixture by mixing glass powders 1 and 2, each having a predetermined composition, with each other; and producing a calcined product by granulating, molding, and heating the powder mixture. This method makes it possible to obtain readily machinable high strength glass ceramics of a novel composition, which exhibit a heat resistance of not less than 1000.degree. C., which excel in mechanical strength and electrical insulation performance, and which allow precision machined parts and large-sized products to be produced with ease.
