摘要： Provided is a heat reflective member, which is prevented from braking even in a high-temperature environment. It generates no dust in use, and can be washed with a chemical liquid. The heat reflective member has a laminated structure in which quartz glass layers are formed on an upper surface and a lower surface of a siliceous sintered powder layer. The heat reflective member includes: an impermeable layer which is formed at a portion of the siliceous sintered powder layer at an end portion of the heat reflective member, which has a thickness at least larger than half of a thickness of the siliceous sintered powder layer, and through which a gas or a liquid is prevented from penetrating; and a buffer layer which is formed between the impermeable layer and the siliceous sintered powder layer, and which changes in density from the impermeable layer toward the sintered powder layer.

摘要： The present invention is a method for producing a quartz glass crucible for pulling a single crystal silicon from a silicon melt held therein, including the steps of: producing a quartz glass crucible having an outer layer including an opaque quartz glass containing bubbles therein and an inner layer including a transparent quartz glass containing substantially no bubbles; roughening a region of an inner surface of the produced quartz glass crucible, the region being in contact with the silicon melt when holding the silicon melt; and heating the quartz glass crucible having the roughened inner surface to crystallize a surface of the roughened region. This can produce a quartz glass crucible for pulling a single crystal silicon which can suppress generation of a brown ring on the inner surface of the crucible during pulling the single crystal silicon and can suppress crystallinity disorder of the single crystal silicon.
