• Method for manufacture of silicon carbide
  申请人：Asahi-Dow Limited

  公开号：US04410502A1

  公开（公告）日：1983-10-18

  Silicon carbide of improved quality is obtained by using a liquid silicic acid or modified liquid silicic acid as a silicic substance and carbon in a powdered form, a precursor of carbon in a powdered form, or a precursor of carbon in the form of a solution as a carbonaceous substance, and thermally treating these raw materials in a non-oxidative atmosphere. The silicon carbide thus produced is finely divided and in high-purity and suitable for use as raw material for the production of high-strength sintered articles.

  使用液态硅酸或改性液态硅酸作为硅质物质，以粉末状碳、粉末状碳前体或溶液形式的碳前体作为碳质物质，并在非氧化气氛下对这些原材料进行热处理，可以获得改善质量的碳化硅。因此生产的碳化硅细分且高纯，适合用作高强度烧结制品的原材料。

  For producing crystalline sodium silicates having a layer structure, an SiO.sub.2 /Na.sub.2 O molar ratio of (1.9 to 2.1):1 and a water content of less than 0.3% by weight from a waterglass solution containing at least 20% by weight of solids, the waterglass solution is obtained by reacting quartz sand with sodium hydroxide solution at an SiO.sub.2 /Na.sub.2 O molar ratio of (2.0 to 2.3):1 at temperatures of 180.degree. to 240.degree. C. and pressures of 10 to 30 bar. This waterglass solution is treated in a spray-drying zone with hot air at 200.degree. to 300.degree. C. for a residence time of 10 to 25 seconds and at a temperature of the exit gas leaving the spray-drying zone of 90.degree. to 130.degree. C., to form a pulverulent amorphous sodium silicate having a water content (determined as the loss on ignition at 700.degree. C.) of 15 to 23% by weight and a bulk density of more than 300 g/l. The pulverulent, amorphous, water-containing sodium silicate is introduced into an obliquely arranged rotary kiln fitted with devices for moving solids and treated therein with flue gas in countercurrent at temperatures from more than 500.degree. up to 850.degree. C. for 1 to 60 minutes to form crystalline soidium silicate. The rotary kiln is here insulated in such a way that its outside wall temperature is less than 60.degree. C. Finally, the crystalline sodium silicate emerging from the rotary kiln is comminuted by means of a mechanical crusher to grain sizes of 0.1 to 12 mm.
