摘要： A ceramic heater device for use in a glow plug for a diesel engine has a gradually varying cross-sectional composition which eliminates distinct interfacial junctions between a resistive layer, an insulative layer and a highly conductive layer. The heater is manufactured by slip casting where the proportions of conductive and non-conductive ceramic particles in a slip are varied as the slip is passed through an absorbent mold.

摘要： A sheath heater includes a metal sheath, a coil-like heater, and a heat-resistant insulating powder. The starting form of the metal sheath has a small-diameter cylindrical portion at its distal end and is formed to have a substantially tubular shape as a whole. The heater is fabricated by inserting the coil-like heater in the sheath. The heat-resistant insulating powder is charged in the sheath and holds the coil-like heater in the sheath so that the coil-like heater is electrically insulated from the sheath. The distal end portion of the sheath is melted and so that the confronting end of the coil-like heater is buried so as not to be exposed on the outer wall of a closing portion at the distal end of the sheath. The melting of the sheath end can be done by using plasma, electron-beam or laser welding techniques.

摘要： An electrically insulating ceramic sintered body suitably used in a ceramic glow plug, for example, is formed by firing a mixed powder of 75 to 95 vol % of a basic material, 25 to 5 vol % of an additive and a sintering aid. The basic material is composed of at least one material selected from the group consisting of silicon nitride, aluminum nitride, and .beta.-sialon. The additive is composed of at least one material selected from the group consisting of silicide, carbide, nitride, and boride of metal, the additive having a thermal expansion coefficient larger than that of the basic material. And the sintering aid is composed of one of alumina in an amount of 3 to 50 wt % of the total amount of the basic material and the additive, and spinel in an amount of 2 to 15 wt % of the total amount of the basic material and the additive. The sintered body has the structure that particles of the additive cohere and the cohering additive particles are dispersed in particles of the basic material so as to be surrounded by the particles of the basic material and separated from adjacent cohering additive particles by the particles of the basic material. When the sintered body is used as a heater supporting member of the ceramic glow plug, the thermal expansion coefficient thereof can be controlled in accordance with that of the heater, and a high specific resistance of not less than 10.sup.5 .OMEGA. cm can be obtained.

摘要： A method of making a hot surface igniter is described. A silicon carbide composition that includes both fines fraction and a coarse fraction is sintered in a nitrogen and argon reducing atmosphere in a manner that controls the incorporation of nitrogen with in the lattice of recrystallized silicon carbide. The controlled incorporation of nitrogen in the lattice provides enhanced control over heating and electrical properties, while simultaneously achieving a lower surface area fully recrystallized structure for oxidation resistance and long service life.
