Abstract:
Carbon-containing black glass compositions of matter having the empirical formula SiC. sub. x O. sub. y in which x ranges from about 0. 5 to about 2. 0, and y ranges from about 0. 5 to about 3. 0, wherein the carbon content of the black glass ranges from about 10% to 40% by weight, are prepared by pyrolysis of a cyclosiloxane polymer in a non-oxidizing atmosphere at a temperature from about 750. degree. C. to about 1400. degree. C.
