摘要： A novel photocurable composition suitable for preparing, for example, release papers is proposed which is formulated with photocrosslinkable organopolysiloxanes necessitating no conventional photosensitizers. Thus, the composition comprises(a) an organopolysiloxane having at least two mercaptoalkyl, e.g. mercaptopropyl, groups bonded to the silicon atoms in a molecule,(b) an organopolysiloxane having at least two alkenyl, e.g. vinyl groups directly bonded to the silicon atoms in a molecule, and(c) an organopolysiloxane having at least one benzoin group ##STR1## where Ph is a phenyl group, bonded to the silicon atom in a molecule, which component (c) serves as a photosensitizing ingredient. Alternatively, the inventive composition comprises (a) a mercaptoalkyl-containing organopolysiloxane as above and (b') an organopolysiloxane having, simultaneously, at least two alkenyl groups and at least one benzoin group directly bonded to the silicon atoms in a molecule, which component (b') serves both as the crosslinking agent and as the photosensitizing ingredient simultaneously. Owing to the unquestionable affinity of the photosensitizing ingredient with the other components, the inventive compositions have very high sensitivity in photocuring along with several other advantageous characteristics.

摘要： A powdery mixture of a fine silicon carbide powder admixed with boron or a boron compound, e.g. boron carbide, titanium boride and boron oxide, as a sintering aid is compression-molded into a green body which is subjected to a sintering treatment into a sintered body. Different from conventional methods in which the sintering treatment is performed always in an atmosphere of an inert gas, e.g. argon, the sintering treatment in the inventive method is performed in an atmosphere of a rare gas containing 0.005-5% by volume of nitrogen. The sintered body of silicon carbide obtained by this method has an outstandingly high electric volume resistivity of 10.sup.10 to 10.sup.13 ohm.cm and a coefficient of thermal conductivity of 100-220 W/m.K.

摘要： Hollow ceramic fibers are prepared by melt spinning an organic silazane polymer, infusibilizing the fiber to form an infusible layer on the surface, and pyrolyzing the fiber to obtain a ceramic fiber having an empty interior. The infusibilizing step includes two steps of treating the fiber with a gas containing the vapor of an infusibilizing silicon, boron, phosphorus or metal compound and further treating with a water vapor-containing gas or ammonia-containing gas. The surface infusible fibers are efficiently sintered into hollow ceramic fibers without fusion bond.
