SHAPED BODIES OF CALCIUM SILICATE

摘要

A shaped body of calcium silicate characterized by being composed of globular secondary particles interconnected with one another and each made up of lath-like xonotlite or foshagite crystals having been three-dimensionally interlocked with one another and having an index of crystallite antigrowth of at least 15, the globular secondary particles having had an outside diameter of about 10 to about 80 mu m and an apparent density of up to 0.13 g/cm3 and having been in the form of a shell with a hollow interior space and a thickness of about 0.3 to about 10 mu m before being shaped into the body.
