| abstract |
A process for strengthening or toughening a phosphate glass the process comprising contacting the surface of the phosphate glass with a solution of a carboxylic acid in a liquid diluent, the carboxylic acid comprising an amino-carboxylic acid, or a hydroxy-carboxylic acid, or a mixture of an amino-carboxylic acid and a hydroxy-carboxylic acid. Particularly useful is an aqueous solution of an amino-polycarboxylic acid. |
