Study of the Effect of pH Regulators and Polyelectrolytes on Lithium-Aluminum Silicate Glass Aqueous Suspension Parameters and Casting Properties

Resumo

Wet milling is used to prepare lithium-aluminum silicate glass suspensions. The possibility is studied of using electrostatic and electrosteric stabilization methods for controlling aqueous suspension parameters with the aim of reducing the duration of green workpiece setting with required density and porosity. Additives used are orthophosphoric and hydrochloric acids, aqueous ammonia solution, and also polyacrylic acid (PAA), and PAA sodium and ammonium salts.
