A heat-resistant member 10 according to the present invention includes a member to be protected 12 and a metal oxide ceramic protective layer 14 which is disposed on part of or all surfaces of the member to be protected 12 and which has a porosity of 0 percent by volume or more and 5 percent by volume or less. This heat-resistant member 10 is produced through the step of forming a protective layer by firing a member to be protected 12 provided with a metal raw material in the air in a temperature range lower than the melting point of an oxide of the metal raw material to form a metal oxide ceramic protective layer 14 having a porosity of 0 percent by volume or more and 5 percent by volume or less on part of or all surfaces of the member to be protected 12. In the forming of a protective layer, the member to be protected 12 provided with the metal raw material may be fired within the range of 400°C or higher and 900°C or lower.

摘要:
The present disclosure relates to a heat-emitting composition coated on the surface of a heat-resistant ceramic ware and emitting heat by absorbing microwaves, which includes a heat-emitting metal oxide material and a binding material, a transfer paper for a ceramic ware including same, a far-infrared-emitting ceramic ware including same, and a method for preparing same. The heat-emitting composition coated on the surface of the ceramic ware absorbs microwaves from a microwave oven and emits heat and far-infrared light, such that food can be cooked evenly in short time by the emitted far-infrared light without burning or drying on the food surface. Further, the far-infrared-emitting ceramic ware can be used as a far-infrared-emitting medical device for fomentation. Also, because of superior heat resistance, the far-infrared-emitting ceramic ware of the present disclosure can be directly heated. Accordingly, cooking can be performed using various means such as gas stove, oven, etc. in addition to the microwave oven.
摘要:
A method of making ceramic electrode materials comprising intimate mixtures of two or more components, including at least one nanoscale ionically conducting ceramic electrolyte material (e.g., yttrium-stabilized zirconia, gadolinium-doped ceria, samarium-doped ceria, etc.) and at least one powder of an electrode material, which may be an electrically conducting ceramic electrode material (e.g., lanthanum strontium manganite, praseodymium strontium manganese iron oxide, lanthanum strontium ferrite, lanthanum strontium cobalt ferrite, etc.) or a precursor of a metallic electrode material (e.g., nickel oxide, copper oxide, etc.). The invention also includes anode and cathode coatings and substrates for solid oxide fuel cells prepared by this method.
摘要:
An apparatus for removing soot from diesel engine exhaust streams at temperatures below 150˚C is provided. Although the use of particulate filters for removing carbonaceous soot from such exhaust streams is known, such systems are either active or operate under high temperatures, i.e. in excess of 300˚C. The claimed apparatus includes a flow through support device composed of ceramic, such as cordierite or silicon carbide, or a primarily nonferrous metal or stainless steel and coated with an oxide formation comprising hematite and bixbyite in a ratio from 1 :1 to 9:1. The claimed apparatus can also include a diesel particulate filter coated with a coating comprising tin, aluminum and zirconium oxides prepared by a co-precipitation process and thereafter coated with platinum or other precious metal.
