Preparation of Highly Concentrated Binder Suspensions Based on Magnesium Aluminum Silicate Glass

Resumo

Wet milling in a ball mill is used to prepare a suspension based on amorphous and crystallized magnesium aluminum silicate glass. The stabilizing additives used are hydrochloric and oxalic acids, and also an aqueous ammonia solution. Raw material is molded by slip casting in porous molds. Optimum ranges are provided for magnesium aluminum silicate glass suspension casting parameters in order to prepare green workpieces with not more than 30% porosity.
