摘要:
A carbon material, a jig, and a method of manufacturing the carbon material are provided that can prevent dust emission and also improve the temperature resistance under a nitrogen atmosphere. In a carbon material having a carbon substrate and a metal carbide layer formed on a surface of the carbon substrate, the metal carbide layer includes molybdenum carbide and/or iron carbide. The carbon substrate embedded in a surface modifying agent containing a pyrolytic hydrogen halide generating agent and molybdenum particles and/or iron particles is heat-treated together with a carbon member other than the carbon substrate.

By inhibiting generation of particles, a carbon material and a method of manufacturing the carbon material are provided that can be used in the field of semiconductor manufacturing or the like, in which low dust emission is considered important. A carbon material having a chromium carbide layer formed on a surface of a carbon substrate. The chromium carbide layer is composed of Cr 3 C 2 . The carbon material can be manufactured through a first step of forming a chromium carbide layer containing a chromium carbide other than Cr 3 C 2 on a surface of a carbon substrate, and a second step of heat-treating the carbon substrate under a reducing atmosphere to convert the chromium carbide other than Cr 3 C 2 into Cr 3 C 2 .

摘要:
A method of manufacturing a carbon material that can prevent formation of unevenness of a coating film and degradation in adhesivity of the coating film, by inhibiting a carbon substrate from forming a portion in which a metal carbide layer is not formed. The method is characterized by including a first step of causing metal powder to adhere to a carbon substrate by coating the carbon substrate with a slurry containing the metal powder and polyvinyl alcohol as a binder, and a second step of heat-treating the carbon substrate to which the metal powder has adhered in a vessel containing an atmosphere of hydrogen chloride gas.
摘要:
A carbon material and a method of manufacturing the same are provided that make it possible to form a layer of a metal that is highly reactive with carbon, such as tungsten, on a carbon substrate while at the same time inhibiting an increase in manufacturing cost and a degradation of processing accuracy. The carbon material has a carbon substrate 2, a first layer 12, and a second layer 13. The first layer contains a carbide of a transition metal. The second layer contains a second metal and/or a carbide of the second metal and a carbide of the transition metal, the second metal being at least one metal selected from the group of metals consisting of Group 4 elements, Group 5 elements, and Group 6 elements. The first and second layers are formed on a surface of the carbon substrate in that order.
摘要:
When treated with a halogen gas, a carbon material can inhibit emission of an impurity after the treatment. A method of manufacturing the carbon material is also provided. A carbon material is subjected to an annealing process under a reduced pressure of from 1 to 10000 Pa in a H 2 gas atmosphere at 500°C to 1200°C. The duration of the annealing process is from 1 minute to 20 hours. This makes it possible to control the concentration of the halogen emitted, such as chlorine, to 5 ppb or less.
