Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form hydrogen bonds with ... Borosilicate glass is created by combining and melting boric oxide, silica sand, soda ash, and alumina. Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new techniques were required for industrial production. In addition to quartz, sodium carbonate, and aluminium oxide traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass.

Web7.2 Glass structure theories. Goldsmith (1926) was the pioneer in studying glass structure and setting the parameters required for any oxide to form a glass. His theory stated that any oxide, Rm O n, having ionic radius ratio of the cation, R, to oxygen ion, O, in the range of 0.2 to 0.4 would form a glass. share schedule
