摘要： Ceramics having excellent resistance against fusing damages due to molten metal or other inorganic material are disclosed. When in contact with a molten material such as molten metal or glass, members made of conventional boron nitride (BN) ceramics are easily damaged at the contact portion. The resistance against molten materials can be markedly improved by adding aluminum nitride (AlN) in an amount of 1 AlN

摘要： A single sinter of BN or a high-strength composite sinter formed of BN and other ceramics and a process for their production. The process comprises using, as a partial or whole starting material for the BN component, an amorphous BN powder or a powder capable of producing amorphous BN in the course of the sintering step. The resulting boron nitride sinter is effectively used as, for example, electronic components.

摘要： An h-BN ceramic having excellent resistance against fusing damage caused by melts such as metal or glass is disclosed. Incorporation of 50 % or more h-BN and 1 to less than 50 % of a composite compound composed of two or more compounds selected from among AlN, Si3N4, Al2O3 and SiO2 in a sinter serves to markedly improve its resistance against the fusing damage. Further incorporation of at least one compound selected from among AlN, Si3N4, Al2O3 and SiO2 in an amount of less than 30 % in addition to the above-mentioned composite compound serves to remarkably improve the wetting resistance and thermal shock resistance as well as the resistance against the fusing damage.

摘要： Structures of a thermometer comprising an integral unit of a thermo-couple and a protective pipe, a thermometer capable of simultaneously measuring the temperatures of multiple points, and a thermometer device comprising a combination of various external protective pipes and the thermometers described above for measuring the temperature of a molten steel or glass. An alumina sintered body comprising at least 99.5 wt.% of aluminum oxide and a composite plastic body of coarse crystal grains having a size of at least 5 mu m and fine crystal grains having a size of not greater than 3 mu m, and used as a material of an insulating ceramic protective pipe of the thermometer device described above. A mixture is prepared by adding 2 to 20 wt.% of a coarse alumina raw material and a crystallization assistant to a fine alumina material, formed and then sintered at a low temperature of less than 1,500 DEG C, preferably below 1,400 DEG C. Because deterioration of thermocouple wires is less, the durability is high, the handling is easy and the response is high. The device is particularly effective for measuring high temperatures in a contaminated environment, and exhibits remarkable measurement performance and economical efficiency when used in a diffusion furnace for semiconductor manufacture where multi-point measurement is necessary.

摘要： A mold for use in the pad molding of powders of inorganic, organic or metallic materials. As a basic material that constitutes the mold, the invention uses a single material which exhibits changes of states, such as from liquid to gas or solid, softening - - hardening and low viscosity - - high viscosity depending on temperature, or a mixture of this material with other powder or a material impregnated with this material. A mold cavity is formed at a temperature at which this material is hardened or highly viscous and, after molding, a pad molding product is released from the mold at a temperature at which this material is liquid, softened or lowly viscous, or while this material is dissipated from the mold. This operation can prevent the pad molding product from being damaged during mold release operation.

摘要： A sheet-like heat generation body for use in a microwave oven, which absorbs microwave and generates heat to irradiate food to be cooked. This heat generation body comprises a conductive film, which is made of a crystalline carbon as its principal component, and is formed on a sheet-like base material. The heat-generating body is prepared using a heat-resistant base material and an inorganic bonding agent applied to its surface. Specifically, a heat-resistant base is coated with a mixture of a microwave-absorbing and heat-generating material as its principal component and an agent for hardening an inorganic bonding agent to be applied later. After the mixed agent is dried, it is impregnated with the inorganic bonding agent.

摘要： This invention relates to a material which heats and cooks foods from outside by absorbing microwaves of an electronic range and by generating heat. A conductive substance or a nonconductive compound containing transition metals of atomic number 21-29 is mixed in a base material having an Fe group oxide as a principal component. Since the material has a rapid heat generating speed, the temperature in heat-generation is high, and further the material is cheap; it is effective as a material generating heat by absorbing microwaves.
