ABSTRACT:
A range of titano-borate glass compositions e.g. for use as cross linking agents in the preparation of polycarboxylic acid cements. The glass may contain one or more further metal oxides, for example calcium and/or zinc, and typically comprises 25-40 mole % calcium, 45-65 mole % boric oxide and up to 15 mole % titanium dioxide. The specification also describes the preparation of polycarboxylic acid, typically polyacrylic acid, cements incorporating the glasses.
