摘要:
A method of treating a carbon-carbon structure is provided. The method includes the step of infiltrating the carbon-carbon structure with a ceramic preparation (206, 306, 408) comprising an oxide compound and at least one of a boron compound or an oxide-boron compound to obtain a uniform distribution of the ceramic preparation within a porosity of the carbon-carbon structure. The carbon-carbon structure may be densified by chemical vapor infiltration (CVI) and heat treated to form borides (210, 312, 410). Heat treating the carbon-carbon may comprise a temperature ranging from 1000°C to 1900°C.

A ceramic member in which the metal layers with high void ratio are sufficiently sintered to lower a residue of resin is produced. The method for manufacturing a ceramic member which comprises a step of forming a stacked compact from a plurality of metallic paste layers containing a metal component M 1 that are stacked one on another via ceramic green sheets, and a step of firing the stacked compact, wherein at least one of plural metallic paste layers is formed as a second metallic paste layer that has the mass percentage X higher than that of the metallic paste layer that adjoin therewith in the stacking direction and a ceramic powder is contained in the second metallic paste layer in the step of forming the stacked compact, the mass percentage X being the proportion of the metal component M 1 to the total metal content in the metallic paste layer.

A handle substrate is composed of a translucent alumina sintered body containing a sintering aid including at least magnesium. A concentration of magnesium at a bonding face of the handle substrate to a donor substrate is half or less of an average concentration of magnesium of the handle substrate.
