| description | The purpose of the present invention is to provide: a polycrystalline SiC molded body which is capable of achieving uniform plasma etching when used as an electrode; and a method for producing the polycrystalline SiC molded body. The main surface of the polycrystalline SiC molded body has a Wa (0-10 mm) of 0.00-0.05 [mu] m or less, a Wa (10-20 mm) of 0.13 [mu] m or less, and a Wa (20-30 mm) of 0.20 [mu] m or less.
本发明旨在提供能够在被用作电极时实现均匀的等离子体蚀刻的多晶SiC成型体及其制造方法。多晶SiC成型体主面的Wa(0～10mm)为0.00～0.05μm以下，Wa(10～20mm)为0.13μm以下，Wa(20～30mm)为0.20μm以下。 |
