Method for preparing binder for refractory powders |
摘要 |
A method for preparing a hybrid binding liquid comprises coloidal silica derived from the hydrolysis of an alkyl silicate and from an acidic organo-aqueous silica sol. More than 50% by weight of silica is derived from the sol by the expedient of replacing part of the water in a commercially available silica sol either by a polyhydric alcohol or by silica.
