CRUDE CONCENTRATE AND CHARGE FOR MAKING SILICATE GLASS Russian patent published in 2016 - IPC C03B1/00 C03C1/02

Abstract RU 2597008 C1

FIELD: materials.

SUBSTANCE: invention relates to making new synthetic materials for production of silicate glass basing on pre-processing basic traditional raw materials with partial or complete replacement of part of them with hydroxides of alkali and alkali-earth metals. Crude concentrate for producing silicate glass has the chemical composition as of Na₂O, SiO_2,is determined by the specified composition of silicate glass with the volume weight of 1.22 t/m³, phase composition is represented by amorphous and main crystalline phases - β-quartz and sodium metasilicate with traces of residual NaOH Na₂CO₃.

EFFECT: technical result is reduction of temperature and reduced time of boiling silicate glass without or with reduced amount of brightening additives.
