    摘要： Process for the determination of the boron content of pure halogensilanes pecially silicon tetrachloride and trichlorosilane, which contain up to 0.1% of atoms of acceptors and donors, which comprises the steps of converting the halogen silanes into the gaseous state in a testing apparatus by contacting said halogensilanes with an evaporator surface heated to a temperature ranging from 80.degree. C to 350.degree. C, passing the generated gases to a support heated to the decomposition temperature of the gases whereby the released silicon is deposited on the support, removing the support and the deposit thereon from the testing apparatus and determining the boron content by calculation from the measured value of the specific resistance of the support plus the deposited silicon. It should be understood that all parts of the testing apparatus which come into contact with the generated gas, with the exception of the support heated to the required deposition temperature, should be at the temperature above 80.degree. C, but below the decomposition temperature of the halogensilane.

    摘要： A method for lowering the risk of contamination during comminution of solid silicon fragments produces in a first step a temperature gradient in the solid silicon fragments. This temperature gradient results from the action of heat applied from the outside. A second temperature gradient is then produced, whose direction is rapidly at least partly reversed in a second step. This treatment effects a decompacting which makes it possible to use, in a subsequent mechanical comminution step, tools whose contact surfaces are composed of silicon or of hard materials, for example, based on nitride or carbide. The product obtained is remarkable for its uniform grain size distribution and also for its high purity in fine grain size categories. In addition, the low forces required for the comminution makes possible a longer service life for the tools used.
