The present advent relates to a used for pulling silicon solitary crystal quartz glass crucible, which comprises a together with the opening and closing the aperture dense sintering sector quartz goblet body, inside the quartz a glass body in the airtight glaze, lateral with porous. The modern day invention relates to a method pertaining to manufacturing quartz glass crucible crucible, in which at least a portion associated with an inner part of the substrate, wherein the crystallization promoter to promote the formation of cristobalite. In order to provide an extended service lives with the green nature of the quartz cup crucible inexpensive manufacturing technique, the invention strongly recommended, the crystallization promoter and a lowering substance is definitely added to the inner layer. The invention provides a quartz crucible for polysilicon crystallization and its making method, the crucible in regular sq . structure, structure of the mass ratio of silica: < 600ppm > 99. 7Wt%, alumina, straightener oxide < 30ppm. The task: first the raw materials of high purity quartz input granulation equipment of wet granulation, particle size control in 70 ~ m 95 ~ meters; then the slurry stirring, located 24 to 48 hours after 2 ~ 3bar pressurized is inserted into a plaster mold, pre grouting with slight oscillation and stationary discharge five ~; in 8 several hours, full lacks after launch, and within the dryer blow drying; finally the embryoid physiques in a kiln for sintering, opaque quartz crucible. The scheme retreats into the high pure quartz material shot molding, sintering the crucible internal company structure is extremely uniform, has excellent energy shock stableness and anti cracking potential, satisfy the polycrystalline silicon ingot production process requirements. http://www.quartzcrucible1986.com
