B-SIC LAMELLE, PREPARATION PROCESS, CERAMICS AND REFRACTORIES CONTAINING THE SAME

摘要

Flaky beta -SiC mainly composed of beta -SiC which is obtained from an organic silicon polymer containing the carbon and silicon atoms as the major skeletal component and the method for producing such flaky beta -SiC are disclosed. Such beta -SiC is especially utilized as the starting material for ceramics having a laminar structure as well as for the refractories. The ceramics and refractories provided with such beta -SiC have excellent resistance to thermal shock, to thermal fatigue as well as to oxidation.
