Crack-proof quartz ceramic crucible

Abstract

This utility model relates to the field of crucible technology, specifically a crack-resistant quartz ceramic crucible, comprising a crucible body with an open top and an outwardly flared edge. The crucible body includes a crack-resistant layer, a protective layer on the inner surface of the crack-resistant layer, a mesh buffer layer on the outer surface of the crack-resistant layer, and a metal wire mesh in the center of the crack-resistant layer. The metal wire mesh is integrally formed with the quartz slurry poured into the mold. The metal wire mesh withstands tensile and compressive forces, effectively dispersing and bearing the stress generated during use, significantly enhancing the overall structural stability of the crucible and reducing the risk of cracking due to stress concentration. The mesh buffer layer buffers and disperses stress. The protective layer on the inner surface effectively prevents the high-temperature melt from eroding the inner wall of the crucible and reduces damage to the crucible material from chemical reactions. The crucible can better adapt to temperature changes in high-temperature environments, reducing cracks caused by thermal expansion and contraction and extending the service life of the crucible.
