    • A novel method is proposed for the preparation of a calcium silicate powder particularly useful as a filter aid in the filtration of an acidic aqueous liquid by virtue of the extremely high acid resistance of the calcium silicate powder. The inventive method comprises a hydrothermal reaction of a blend of a silica-containing material and calcium oxide or hydroxide in a specified molar ratio under specified reaction conditions to form calcium silicate, which is then subjected to a heat treatment at 800.degree.-1200.degree. C. for 0.5-2 hours. An improvement can be obtained in the clarity of the filtrate obtained by the filtration using the calcium silicate powder prepared by the inventive method as a filter aid when the hydrothermal reaction for the preparation thereof is conducted in an aqueous solution of potassium hydroxide in a specified concentration.
    • 提出了一种制备硅酸钙粉末的新方法,该硅酸钙粉末由于硅酸钙粉末的极高耐酸性而特别可用作过滤酸性含水液体中的助滤剂。 本发明的方法包括在规定的反应条件下将含二氧化硅的材料与氧化钙或氢氧化物的混合物以规定的摩尔比水热反应,形成硅酸钙,然后在800-1200℃下进行热处理 0.5-2小时。 在通过本发明方法制备的硅酸钙粉末过滤获得的滤液的澄清度可以获得,当其制备的水热反应在规定浓度的氢氧化钾水溶液中进行时,作为助滤剂 。
