    摘要： Silicon nitride sintered bodies are disclosed which contain silicon carbide therein and in which intergranular phases between silicon nitride particles are substantially crystallized. Further, a manufacturing method of the sintered bodies is disclosed, in which a silicon carbide powdery raw material is used as an additive when preparing raw powders and the intergranular phases are crystallized during a temperature descending stage following a firing. Silicone carbide effectivley promotes densification of the structure of the sintered body and crystallization of the intergranular phases, thereby making it possible to provide the sintered bodies having intergranular phases with little glass phases uncrystallized and excellent high-temperature strengths.

    摘要： Silicon nitride sintered bodies are disclosed which contain silicon carbide therein and in which intergranular phases between silicon nitride particles are substantially crystallized. Further, a manufacturing method of the sintered bodies is disclosed, in which a silicon carbide powdery raw material is used as an additive when preparing raw powders and the intergranular phases are crystallized during a temperature descending stage following a firing. Silicon carbide effectively promotes densification of the structure of the sintered body and crystallization of the intergranular phases, thereby making it possible to provide the sintered bodies having intergranular phases with little glass phases uncrystallized and excellent high-temperature strengths.

    摘要： A reaction vessel including an oxygen-containing gas chamber separated from a source gas chamber by an oxygen-permeable membrane that allows oxygen selectively to pass therethrough to contact and react with source gas contained in the source gas chamber. The ratio of at least one of (i) the volume of the oxygen-containing gas chamber to the total volume of the vessel and (ii) the volume of the source gas chamber to the total volume of the vessel, is outside a range within which explosion would occur if the oxygen-containing gas and source gas were allowed to combine directly. Preferably, the ratio also is outside a range within which explosion would occur if the oxygen-containing gas and products resulting from reactions between oxygen supplied through the oxygen-permeable membrane and the source gas were allowed to combine directly. The vessel is safer to operate in that the risk of explosion, due to direct mixing of the gases when the oxygen-permeable membrane is damaged or cracked, is greatly reduced.

    摘要： An apparatus for recovering, refining, and storing hydrogen gas, includes: a recovery and refinement line for recovering and refining hydrogen gas used for a hydrogen furnace or used as a process gas; a storage tank for storing refined gas; and a resupply line for resupplying a stored gas to the hydrogen furnace or as a process gas. A palladium film is installed in the recovery and refinement line and lets hydrogen gas permeate the palladium film so as to be refined.
