    摘要: The invention relates to the manufacture of high purity germanium for the manufacture of e.g. infra red optics, radiation detectors and electronic devices. GeCl4 is converted to Ge metal by contacting gaseous GeCl4 with a liquid metal M containing one of Zn, Na and Mg, thereby obtaining a Ge-bearing alloy and a metal M chloride, which is removed by evaporation or skimming. The Ge-bearing alloy is then purified at a temperature above the boiling point of metal M. This process does not require complicated technologies and preserves the high purity of the GeCl4 in the final Ge metal, as the only reactant is metal M, which can be obtained in very high purity grades and continuously recycled.

    摘要: The immersed surface area of one of the electrodes in a conventional electro-chemical bath is accurately determined, so that the bath may be operated at an optimium current density, to obtain high quality electro-plating or electro-polishing. The current density is measured as a certain amount of current over the immersed area of the electrode. For any given area, the current density may be varied by varying the current flow.The potential between the bath and the electrode of interest is measured when no current is being conducted through the bath. A short pulse of current is then passed through the bath from one electrode to the other; and immediately thereafter the potential between the bath and the electrode of interest is again measured. These two potentials are then compared, and the potential difference is used to determine the immersed surface area of the electrode of interest according to a mathematical relationship corresponding to such electro-chemical baths. The immersed surface area of the electrode of interest can also be determined by varying the pulse current amplitude and frequency to obtain a certain predetermined difference between the potential values, measured as described above. The pulse current amplitude and frequency are then used to determine the immersed surface area of the particular electrode according to another mathematical relationship corresponding to such electro-chemical baths.

    摘要: The invention relates to the manufacture of high purity silicon as a base material for the production of e.g. crystalline silicon solar cells. SiCU is converted to Si metal by contacting gaseous SiCU with liquid Zn, thereby obtaining a Si-bearing alloy and Zn-chloride, which is separated. The Si-bearing alloy is then purified at a temperature above the boiling point of Zn. This process does not require complicated technologies and preserves the high purity of the SiCU towards the end product, as the only reactant is Zn, which can be obtained in very high purity grades and continuously recycled.
