GLASE COMPOSITIONS Russian patent published in 2011 - IPC C03C1/02 C04B41/86 

FIELD: chemistry.

SUBSTANCE: present invention relates to boron-containing compositions for use in glase. Disclosed is a boron-containing composition which is obtained by heating to temperature which is sufficiently high for annealing but insufficient for formation of a homogeneous melt. Said composition contains common components which, during heating, are capable of forming oxides B₂O₃, SiO₂, Al₂O₃, Na₂O and optionally CaO, in the following ratio in wt %: 10-18 B₂O₃, 40-65 SiO₂, 17-32 Al₂O₃, 4-9 Na₂O and 0-10 CaO. Disclosed boron-containing compositions may be used in different glase compositions, including those which do not contain frit, to together with frits which do not contain boron.

EFFECT: obtaining boron-containing glase with low solubility of boron and low power consumption.
