Abstract

The invention discloses a quartz crucible excellent in heat preservation effect. The quartz crucible comprises a quartz crucible body and is characterized a crucible bottom is fixedly mounted at the lower end of the quartz crucible body, a crucible body part is arranged in the middle of the quartz crucible body, the inner surface of the crucible body part is provided with an inner wall, the outersurface of the inner wall is provided with an outer wall, a graphite heat preservation sleeve is fixedly mounted on the outer surface of the outer wall, and a position, close to the inner surface of the inner wall, inside the outer wall is provided with a transparent layer. The quartz crucible has the advantages that the quartz crucible is provided with the graphite heat preservation sleeve, an extruded polystyrene board and a honeycomb core, so that the quartz crucible is resistant to high temperature, and the heat preservation effect of the quartz crucible is improved; meanwhile, graphite heat preservation sleeve dampness can be prevented at the same time to prolong the service life of the graphite heat preservation sleeve; the weight of the graphite heat preservation sleeve is reduced while hardness lowering is avoided; the quartz crucible is convenient for people to use and promising in application prospect.

Description

technical field [0001] The invention relates to the field of quartz crucibles, in particular to a quartz crucible with excellent thermal insulation effect. Background technique [0002] Quartz crucible has the advantages of high purity, strong temperature resistance, large size and high precision, good heat preservation, energy saving, stable quality, etc., and is used more and more widely. The detection of quartz crucibles is a very important link, and the detection of quartz crucibles is developing towards the direction of on-site detection, and quartz crucibles are also widely used in the production of semiconductor silicon wafers; First, the hardness is not enough, it is easy to break, and the heat preservation effect is not good enough. Therefore, we propose a quartz crucible with excellent heat preservation effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a ...
