Abstract: A method of simultaneously producing or co-synthesizing a combination of zeolite X and zeolite A by separately preparing a sodium aluminate solution and a sodium silicate solution, adding the sodium aluminate solution to the sodium silicate solution activated with a relatively small amount of zeolite X seed or bulk product, mixing the solutions together under controlled conditions of temperature and time and heating the mixture to a desired temperature for sufficient time to form a product which is a combination of zeolite X and zeolite A of about 40 percent to 60 percent crystalline with the remainder being an amorphous functional binder.

Abstract: The present invention relates to a process for producing a crystalline synthetic faujasite wherein an activated sodium silicate system is provided by mixing a sodium silicate solution with a seed amount of the faujasite to be produced and the activated sodium silicate system is reacted with a sodium aluminate solution under controlled conditions to thereby form the desired crystalline synthetic faujasite.

Abstract: A wood-bonding adhesive containing as the adhesive base sulfur and a synthetic thermosetting urea resin, phenol resin, melamine resin, resorcinol resin and a flame retardant mixture of compounds selected from styrene, maleic acid related materials, dicyclopentadiene and the like. Also, a method of adhesively bonding wood adherends together and an article bonded by the adhesive are disclosed.

Abstract: A process for the preparation of organic acid halide such as acetyl chloride by reacting an organic acid anhydride with a silicon halide, such as silicon tetrachloride, under conditions such that such the organic acid halide is produced along with silica which is easily separated and disposed of. Preferred conditions include use of a solvent, use of a catalyst and additional process reaction steps whereby by-products are converted to additional organic acid halide and easily disposable waste products.

Abstract: Magnesium metal is produced by the reaction of aluminum metal with a calcium magnesium aluminate slag or with magnesium oxide in the presence of such slag, wherein the silicon dioxide content of the slag is maintained at five weight percent or less. An excess of aluminum metal relative to the amount of magnesium oxide is employed thereby obtaining a high conversion of the magnesium oxide to magnesium metal.

Abstract: Magnesium metal is produced by the reaction of aluminum metal with a calcium magnesium aluminate slag or with magnesium oxide in the presence of such slag, wherein the silicon dioxide content of the slag is maintained at five weight percent or less.

Abstract: Magnesium metal is produced by the reaction of aluminum-silicon alloy with a calcium magnesium aluminate silicate slag or with magnesium oxide in the presence of such slag, at a temperature of about 1,400.degree.-1650.degree. C and a pressure of 25-500 millimeters of mercury.

Abstract: A method of making an aluminum-silicon composite utilizing aluminum-silicon alloy comprising aluminum as the principal metal with silicon, magnesium and copper in substantial amounts and iron, titanium, magnesium and zinc in lesser amounts and a substantial amount of a non-metal filler such as zircon, alumina, zirconia or aluminum silicates.

Abstract: An aluminum composite comprising aluminum as the principal metal, an alkaline earth metal or an alkali metal as a reducing agent, and a substantial amount of a non-metal filler such as zircon, alumina, zirconia or aluminum silicates, and a method of manufacturing said aluminum composite.
