Abstract: A process for preparing a flowable slurry comprising mixing 25-70 wt. % water; an alkaline material selected from the group consisting of chlorosilicon manufacturing byproducts, direct process residue gels, cement kiln dust, and mixtures thereof; and a process aid selected from the group consisting of sucrose, raffinose, lignin, methylglucopyranoside, lactose, fructose, sodium polyphosphate, trehalose and mixtures thereof to form a flowable slurry. This slurry is especially useful in the manufacture of cement.

Abstract: A method of forming a granular siloxane gel having reduced chloride content. The method comprises contacting a chlorosilicon mixture with an aqueous medium at a temperature within a range of about 50.degree. C. to 180.degree. C. to form a granular siloxane gel, and washing the granular siloxane gel with an aqueous solution comprising a surfactant having a HLB number within a range of about 1 to 28.

Abstract: A method for grinding silicon metalloid comprising grinding silicon metalloid in the presence of an effective amount of a grinding aid selected from the group consisting of carboxylic acids comprising at least 8 carbon atoms, alkali metal salts of carboxylic acids comprising at least 8 carbon atoms, and polydiorganosiloxanes.

Abstract: A process for treating a plurality of by-product streams containing chlorosilicon compounds. The process comprises the steps of determining the average SiCl functionality of a plurality of by-product streams comprising chlorosilicon compounds, blending at least two of the by-product streams to form a blended by-product stream having an average SiCl functionality greater than or equal to 2.8, adding to the blended by-product stream a surfactant having a HLB number within range of about 3 to 28, and contacting the blended by-product stream with an aqueous medium at a temperature within a range of about 50.degree. C. to 120.degree. C. to form a granular siloxane gel.

Abstract: A process for reducing the chlorocarbon content of a mixture comprising an organochlorosilane, a chlorocarbon, and a hydrosilane. The process comprises contacting a mixture comprising as a major portion an organochlorosilane and as a minor portion a chlorocarbon and a hydrosilane with an alumina-zirconia cogel to effect formation of a mixture having reduced chlorocarbon content. When the mixture is contacted with the alumina-zirconia cogel the chlorocarbon reacts with the hydrosilane to form a hydrocarbon that is easily separated from the organochlorosilane. The process improves chlorocarbon removal efficiency while maintaining high throughput rates.
