FIBRE GLASS FOR REINFORCING ORGANIC AND/OR INORGANIC MATERIALS Russian patent published in 2010 - IPC C03C3/91 C03C13/00 

FIELD: chemistry.

SUBSTANCE: invention relates to reinforcing fibre glass containing the following components in wt %: SiO₂ 62-63, Al₂O₃10-16, CaO 6-23%, MgO 1 - 3, Na₂O+K₂O+Li₂O 0-2, TiO₂ 0-1, B₂O₃ 0.1 - less than 1.8, Li₂O 0-0.5, ZnO 0-0.5, MnO 0-1, F 0-0.5. These fibres have better mechanical strength properties, resistance to an acidic medium and high temperature resistance, and their composition is not expensive. The invention also pertains to a method of making the said fibres and a composition for making the said fibres.

EFFECT: increased high temperature and acidic medium resistance of the fibre, as well as reduction of harmful emissions into the environment.
