Title:
METHOD FOR PREPARING PRE-REACTED RAW MATERIAL BATCHES FOR THE PRODUCTION OF GLASS FORMULAE
Document Type and Number:
WIPO Patent Application WO2000066505
Kind Code:
A3
Abstract:
The invention relates to a method for preparing pre-reacted raw material batches substantially free from carbon dioxide for the production of glass formulae. Said method involves mixing stoichiometric amounts of substances containing silicon-sodium, silicon-sodium-calcium, silicon-sodium-magnesium, silicon-calcium-magnesium, silicon-sodium-calcium-magnesium molecular systems and mixtures thereof having reaction temperatures not forming a liquid phase, which are selected from invariant points or points in a line connecting invariant points of phase diagrams of said molecular systems with the purpose of obtaining a desired molecular formula.
