摘要： A method for manufacturing a porous body of molybdenum silicide includes the steps of making a bundle of molybdenum pipes by bundling at least seven molybdenum pipes, impregnating inorganic polysilazane into voids formed between portions where molybdenum pipes contact each other, heating the bundle of molybdenum pipes in a non-oxidizing atmosphere at a temperature of 1000.degree. to 1900.degree. C. The bundle has 100 to 1000000 molybdenum pipes. The inorganic polysilazane is made from H.sub.2 SiCl.sub.2.

摘要： Components for semiconductor diffusion furnaces are constructed of a high purity impervious silicon carbide or silicon nitride matrix deposited on a pre-shaped fibrous matrix of silicon carbide, carbon, or carbon coated silicon carbide. The high purity of the matrix prevents undesired gaseous components from contaminating the atmosphere of the furnace, and the fibrous re-enforcement provides strength combined with light weight.

摘要： A novel isotropically reinforced microcomposite is described. An entirely fluid-phase method has been devised for producing the net-shape filamentary structures. The process depends for its success on the ability to generate in situ, within a shaped mold, a three-dimensional random weave of carbon filaments by catalytic decomposition of a hydrocarbon feed. Almost any desired filament filler matrix combination can be produced by utilizing chemical vapor deposition to modify the surface and bulk properties of the filamentary structure. Infiltration of filler matrix materials can be achieved by adaptation of existing materials technologies.

摘要： A heat-insulating lining for a gas turbine which consists of a mat formed of ceramic fibers that is provided on its side facing the hot gas with a metal-oxide-containing layer, especially Al.sub.2 O.sub.3. The mat to be provided with the ceramic layer should possess a gross density of 350 to 450 kg/m.sup.3 and the fibers in the mat which are in contact with the metal oxide-containing layer are to be predominantly so oriented that the longitudinal axis of the fibers forms an angle of 30.degree. to 90.degree. with the metal oxide-containing layer. It is preferred if the fibers form an approximately right angle with the metal oxide-containing layer. The thus made coated heat-insulating linings possess a good mechanical stability with respect to the hot gases as well as an adequate thermo-shock resistance.

摘要： A porous substrate formed from an agglomeration of fibers preferably has a carbonaceous composition. A binder is applied to the substrate. The binder may illustratively be an acrylic or beeswax to vaporize and form pyrolized carbon during pyrolysis or may illustratively be a phenolic resin, a furfural resin or pitch to form pyrolyzed carbon on the fibers during pyrolysis. A mixture of particles having the same approximate size as the diameter of the fibers is then applied to the fibers to become mechanically locked in the substrate pores. The mixture may contain (a) a first material (preferably a compound containing boron) which oxidizes and melts at a relatively low temperature and is relatively viscous when melted, (b) a second material (preferably a compound containing silicon) which oxidizes and has an increased melting temperature and is more viscous than the first material when melted and (c) a refractory material (preferably a compound containing zirconium) having a considerably higher melting temperature oxide than the first and second materials. The first material may be obtained from group 3a of the periodic table, the second material from group 4a of the periodic table and the third material from groups 4b and 5b of the periodic table. An impermeable coating such as a carbide, oxide or a nitride is thereafter applied to the substrate. The impermeable coating tends to crack at elevated temperatures. The adjacent particles in the mixture melt and flow into the cracks to inhibit crack amplification. The ease of flow is dependent upon the proportions of the first, second and third materials in the mixture. The particles displaced in the mixture from the cracks remain mechanically locked to the substrate.
