摘要: The instant invention involves the production of articles exhibiting an internal microstructure and physical characteristics like those of glass-ceramic bodies but which can be formed spontaneously from a molten glass. Hence, in contrast to the production of conventional glass-ceramic articles, no heat treatment of a parent or precursor glass body is required to cause crystallization in situ to occur. More particularly, the instant invention is concerned with the manufacture of highly crystalline glass-ceramic articles, having compositions within the Li.sub.2 O-Na.sub.2 O-Al.sub.2 O.sub.3 -MgO-SiO.sub.2 -F system, wherein a fluormica constitutes the predominant crystal phase, which can be formed spontaneously from a molten glass batch.

摘要: This invention relates to silicate glasses that possess good resistance to chemical attack by both acid and alkaline media, that may be either clear and transparent or colored as desired, and that may have a moderate thermal coefficient of expansion to provide resistance to thermal shock. Such glasses have general application, but find particular utility in tubing and containers for scientific and pharmaceutical glassware.

摘要: Cellular ceramic bodies are produced by frothing a crystal-containing, ion-exchanged gel and setting the gel. An aqueous gel is prepared from a water-swelling mica and is blended in conjunction with a large cation donor, e.g., a potassium salt or silicate glass, and a surfactant to effect frothing of the gel by a shearing action and exchange of large cations with lithium and/or sodium ions from the mica to produce an ion-exchanged gel that sets in controllable manner.
