摘要:
There is provided a ceramic member which is a sintered body containing enstatite and boron nitride as constituents, in which boron nitride is oriented in a single direction, a probe holder formed using the ceramic member, and a manufacturing method of the ceramic member. In the ceramic member, an index of orientation degree is not less than 0.8. In so doing, it is possible to provide a ceramic member which has a free machining property, a coefficient of thermal expansion which is close to that of silicon, and high strength, and a probe holder which is formed using the ceramic member, and a manufacturing method of the ceramic member.

摘要:
An insulation coating method for a metal base comprises a thermal spraying step, an impregnation step, and a beam irradiation step. In the thermal spraying step, a first insulation coating is formed by thermally spraying a first metal oxide to the surface of the metal base. In the impregnation step, pores formed in the surface of the first insulation coating are impregnated with a sol that contains, as a dispersoid, a metal oxide, a hydrate of a metal oxide, or a metal hydroxide. In the beam irradiation step, a second insulation coating that is composed of a second metal oxide is formed by irradiating the first insulation coating and the sol with a high energy beam after the impregnation step.
