摘要： The invention concerns a method for the manufacture of silicon tetrachloride by conversion of a mixture of finely divided and/or amorphous silicon dioxide, carbon and an energy donator with chlorine. Energy donators are metallic or silicon alloys such as silicon, ferrosilicon or calcium suicide. The addition of the donors effects a self-sustaining, exothermic reaction on one hand and a significant lowering of the reaction starting temperature on the other hand. As finely divided and/or amorphous silicon dioxide ashes containing silicon dioxide are primarily used. These are produced by the incineration of silicon-containing plant skeletal structures such as rice husks or straw. Other sources include silicas from the digestion of alkaline earth silicates with hydrochloric acid and filtered particulate from the electrochemical manufacture of silicon, as well as naturally occurring products containing silicon dioxide, such as diatomaceous earth kieselguhr).

摘要： The present invention relates to a method and equipment for production of high purity silicon by reduction of SiCI 4 with molten Zn metal. The method is characterized in that the reduction takes place in contact with a molten salt that dissolves ZnCI 2 . The ZnCI 2 produced during the reduction then dissolves in the molten salt rather than evaporates. The advantage is that gas evolution during the reduction is minimised, leading to higher utilisation of the SiCI 4 and Zn and thereby a higher Si yield. Another advantage is that the molten salt efficiently protects the air sensitive materials, Zn, SiCI 4 and Si, from oxidation during the reduction. The resulting molten salt containing the ZnCI 2 can be used for electrolysis of ZnCI 2 to regenerate the Zn metal. Chlorine evolved during the electrolysis can be used to produce SiCI 4 .
摘要翻译：本发明涉及通过用熔融的Zn金属还原SiCl 4 Si来生产高纯度硅的方法和设备。该方法的特征在于还原与溶解ZnCl 2 2的熔融盐接触进行。在还原过程中产生的ZnCl 2 O 2溶解在熔融盐中而不是蒸发。优点在于还原期间的气体逸出最小化，导致SiCl 4和Zn的利用率更高，从而Si产率更高。另一个优点是熔融盐有效地保护了空气敏感材料Zn，SiCl 4 Si和Si在还原过程中不被氧化。含有ZnCl 2 2的所得熔融盐可以用于ZnCl 2的电解以再生Zn金属。在电解过程中产生的氯可用于生产SiCl 4。

摘要： This invention describes a method of producing aluminium by electrolysis of aluminium chloride, wherein the aluminium chloride is produced from an aluminium oxide containing feedstock by reaction with CO and chlorine to AlCI 3 and CO 2 , and where the CO 2 thus formed is reduced to CO without the use of fossil carbon sources, wherein the said CO is recycled to the aluminium chloride production and wherein the electrolysis of the aluminium chloride forms aluminium metal and chlorine, where chlorine is recycled to the aluminium chloride production. The internal recycling of CO 2 strongly limits CO 2 emissions.

摘要： A process for production of amorphous silica from quartz includes the following steps: Heating (calcination steps) of quartz or another SiO 2 based material with MgCl 2 at a temperature of 800 - 1300 °C wherein the weight ratio of MgCl 2 to quartz is greater than 2 and the presence of water vapour in excess of the stoichiometric amount needed to make MgSiO 3 or Mg 2 SiO 4 ; Leaching at temperatures preferable between 50 and 150 °C of the produced silicate with HCl to form a solution of MgCl 2 with insoluble silica; Separation of insoluble silica from the solution; Recycling of MgCl 2 to the heating step and the HCl solution to the leaching step. Other chlorines such as BeCl 2 , CaCl 2 , SrCl 2 and BaCl 2 may be used in the process instead of MgCl 2 .
