SILICON CARBIDE MEMBER FOR PLASMA TREATMENT DEVICES, AND METHOD FOR MANUFACTURING SAME
It is an object of the present invention to provide a low cost and durable silicon carbide member for a plasma processing apparatus. A silicon carbide member for a plasma processing apparatus of the present invention is obtained by mixing an ±-silicon carbide powder having an average particle size of 0.3 to 3 µm, wherein an amount of metal impurities in the ±-silicon carbide powder is reduced to 20 ppm or less, and a sintering aid comprising B 4 C in amount of 0.5 to 5 weight parts or Al 2 O 3 and Y 2 O 3 in total amount of 3 to 15 weight parts; sintering a mixture of the ±-silicon carbide powder and the sintering aid in an argon atmosphere furnace or a high-frequency dielectric heating furnace; and then processing the resulting sintered body.
