Apparatus for supporting a glass body and manufacturing method for making same

摘要

The apparatus for supporting a glass body is made by a method including the following steps: putting carbon-containing fibers in an axially parallel arrangement and tightly packing them; twisting the resulting tightly packed carbon-containing fiber bundle to form a carbon-containing fiber rope piece and fixing it in a twisted state; then pyrolyzing the resulting carbon-containing fiber rope piece, soaking the pyrolyzed carbon-containing fiber rope piece in a silicon-containing fluid and ceramicizing the carbon-containing fiber rope piece. The supporting apparatus formed by this method includes a gas-permeable body, which has channels or passages through which a gas, such as air, can pass. The channels are inclined at their outlet ends on a gas outlet surface of the gas-permeable body.
