    摘要: A process and apparatus for making a ceramic article, especially pipes and tubes of ceramic material such as silicon carbide, in which the article is formed by projecting a ceramic powder mixture comprising refractory particles and combustible particles against a smooth-surface metal former which is heated to a temperature of at least 850.degree. C. where in the presence of an oxygen-rich gas the combustible particles react exothermically to produce from the refractory particles and the reaction product of the combustible particles a coherent refractory article in the shape of the former.

    摘要: This detector comprises a gas chamber (2) containing plane electrodes (4, 6, 8) delimiting conversion (C) and amplification (A) gaps. One of the electrodes is perforated with holes (18) and forms the detector cathode (6). The distance between the detector cathode and the anode (8) is less than 500 .mu.m. The intensity of the electric field in the amplification gap is ten times higher than the intensity of the electric field in the conversion gap. Application in particle physics, medicine, biology.
