Traditionally, alkali borosilicate systems are used as a source for borosilicate glass production (Cable 2005). Borosilicate glasses are far stronger than “soft” silicate glass and have been used for everything from cookware to nuclear waste containment. A mixed alkali borosilicate glass is currently used as a wasteform for the vitrification of high level nuclear waste (Ewing et al. 1995; Plodinec 2000). In this connection there are numerous investigations of borosilicate glass structure and properties. On the other side borosilicate crystalline materials are studied poorly. Since most known crystalline borosilicates are structurally similar to aluminosilicates (leucite family, feldspars, zeolites and others) well known for their properties, the preparation and investigation of new borosilicate materials is of technological interest.
