Larger water contents of the starting solution are preferred for the production of bulk glasses, while smaller water contents lead to the formation of fiber glasses. The cross-section of glass fibers made by the sol-gel method is cir

The sequence of phase transformation was noncrystalline gel anatase + rutile. Crystallinity of gel powders and gel-monoliths of two compositions in the Na.O-Ba.O.-SiO. system were examined

Morenos therapeutische Philosophie inserted a quartz glass or alumina tube through a waveguide, excited plasmas at 2450 MHz at gas pressures of 100-7000 Pa, and sintered Al.O. and a few other ceramic powders. They heated small pressed compacts for various lengths of time at various temperatures in the plasma and at the same times an
