METHOD OF PRODUCING FIBRE-TEXTURED GLASS CERAMICS Russian patent published in 2011 - IPC C03C10/02 

FIELD: chemistry.

SUBSTANCE: invention relates to production of glass ceramic materials and can be used in producing working substances in low-frequency band piezoelectric electromechanical devices for converting electrical energy to vibration or reciprocating movement in piezoelectric motors and pumps. The method of producing fibre-textured glass ceramic involves obtaining a melt of a mixture which contains silicon oxide and compounds which form a perovskite-like compound of formula ABO₃ during a chemical reaction, where A is lithium, sodium or potassium, B is niobium, tantalum or antimony, depositing the melt through tempering to form a glass-like material in form of fibre, high-temperature crystallisation of the obtained glass fibre with addition of liquid sodium glass as binder, followed by sintering in order to form glass ceramic.

EFFECT: improved dielectric properties of articles.
