Abstract
A method of making a silicon metal containing article is characterized in the following steps. A water vehicle first slurry is formed which contains silicon metal particles, this first slurry being substantially free of ions which would cause a flocculation of the silicon metal particles. An organic vehicle based second slurry is formed which contains a compound which has an ion which would cause flocculation of silicon metal particles contained in a water vehicle slurry. The organic vehicle of said second slurry, however, is effective to suppress formation of ions by the ion forming compound. The first and the second slurries are added to form a castable silicon metal particle containing slurry in which the compound contained in the organic vehicle can form ions when in contact with the water vehicle. The castable silicon metal particle containing slurry is introduced into a casting mold. The castable silicon metal particle containing slurry is permitted to set up in the casting mold by flocculation of the silicon metal particles by the ion of the ion forming compound. The casting mold is removed after said castable silicon metal particle containing slurry has set up, thereby to form the silicon metal containing article.
