摘要： An X-ray mask includes an X-ray transmitting thin film consisting of SiC, a W X-ray absorber formed on one surface of the thin film and having a predetermined pattern, and a support frame arranged on a peripheral portion of the thin film. The thin film is constituted by a plurality of SiC layers having different C/Si composition ratios. When the thin film is formed by a CVD method, the flow rate of a gas containing Si is fixed while a gas containing C or a diluted gas mixture of the gas containing C is changed. Consequently, the visible light transmittance of the thin film is improved.

摘要： A process for producing a refractory material having the form TB.sub.o, e.g. zirconium nitride (ZrN), includes a first step of mixing a first salt having the form TX.sub.n, e.g. zirconium tetrachloride (ZrCl.sub.4) and a second salt having the form A.sub.m B, e.g. lithium nitride (Li.sub.3 N) in a ratio of n/m in a container. The process also includes a second step of igniting the mixture of the first and second salts, e.g. ZrCl.sub.4 and Li.sub.3 N, whereby the refractory material, e.g. ZrN, is produced along with byproducts having forms nAX and (n/m-o)B, e.g. 4LiCl and (1/6)N.sub.2, respectively. The process further includes a third step of separating the refractory material from the byproducts by solvent extraction. The stoichiometric ratio of the second salt to the first salt is n/m, e.g. 4/3. T is selected from the group consisting of transition metals, e.g. zirconium, and tetrelides, i.e. carbon, silicon, germanium, tin and lead. X is selected from the halide group consisting of fluorine, chlorine, bromine and iodine. A is selected from the group consisting of alkali metals, i.e. lithium, sodium, potassium, rubidium and cesium, and alkaline earth metals, i.e. beryllium, magnesium, calcium, strontium and barium. B is a base selected from the group consisting of pnictides, i.e. nitrogen, hosphorus, arsenic, antimony and bismuth, and tetrelides, i.e. carbon, silicon, germanium, tin and lead, m and n are integers and o is a fraction, e.g. 3/3=1.

摘要： Raw material bodies such as briquettes, for use in the production of silicon or silicon alloys, are formed by mixing a pitch and caking coal at a temperature above 100.degree. C. and up to 200.degree. C. to form a pitch/coal alloy. This hot binder composition is mixed with sand and a noncaking carbon carrier at a temperature in this range to form the starting composition from which preforms are pressed. The preforms are subjected to a heat treatment which involves raising the temperature to above 450.degree. C., preferably in a sand filled rotary furnace to harden the preforms into the bodies.

摘要： A system for producing ceramic or cermet material in a plasma type thermal reactor wherein a reactor flame and reactants are introduced into one end of a reaction chamber through which a concentric film of collecting liquid (oil) flows and empties at the opposite end into a pool of collecting liquid. The collecting (and cooling) liquid enters the chamber at the same end the flame enters and forms a liquid wall surrounding the flame that sweeps substantially the whole inner periphery of the walls of the chamber from one end to the opposite end and empties into the pool of collecting (and cooling) liquid. Liquid from the pool is recirculated back to the one end and is filtered to remove the particulate formed from the reactants.

摘要： The instant invention relates to the use of hollow silicon carbide beams as refractory in substantially closed open-arc furnaces used for the carbothermic reduction of metal oxides. The silicon carbide beams are used in areas of the furnace which are exposed to temperatures higher than those tolerated by standard refractories, said areas requiring, in addition, stability to oxidation and reduction type chemical reactions and sufficient electrical resistance to minimize arcing from the exposed electrode. In addition, the invention relates to the use of silicon carbide beams in a two-stage, open-arc furnace for the carbothermic reduction of silicon dioxide to silicon metal.

摘要： A powder composition consisting essentially of an intimate mixture of boron carbide and titanium diboride, the mixture having an average particle size of less than about 0.5 micron, the particles being uniformly dispersed such that elemental analytical techniques show all discrete concentrations of boron carbide and titanium diboride to be less than or equal to about 0.5 micron in diameter, is disclosed. The powder is useful for making a densified ceramic composition comprising titanium diboride grains, having an average grain size of less than or equal to about 3 microns in diameter, uniformly dispersed with boron carbide grains, having an average grain size of less than about 5 microns in diameter. The densified composition exhibits improved hardness and toughness when compared wiht titanium diboride or boron carbide compositions. The powder can be prepared by a process comprising subjecting a stream of reactant gases consisting essentially of a volatile boron source, a volatile titanium source, a volatile carbon source, and a hydrogen source to an amount of laser radiation and at a pressure effective to convert at least a portion of the volatile boron, carbon and titanium sources to an intimate mixture of boron carbide and titanium diboride.
