<p>A silica container for pulling up monocrystalline silicon, the silica container having a straight trunk, a curved portion, and a base portion, wherein the silica container for pulling up monocrystalline silicon is characterized in that the outer side of the silica container comprises opaque silica glass containing gas bubbles, and the inner side of the silica container is composed of transparent silica glass substantially devoid of gas bubbles, a silica-glass layer measuring 20 to 1,000 mum in thickness and containing OH groups in a concentration of greater than 300 mass ppm and equal to or less than 3,000 mass ppm or less being formed on the inner surface of the bottom portion. Provided thereby is an inexpensive silica container for pulling up monocrystalline silicon enabling cavity defects; i.e., voids and pinholes, to be minimized in pulled-up monocrystalline silicon.</p> |
