Heat-resistant quartz crucible and manufacturing method thereof
The invention relates to the technical field of quartz crucible production, in particular to a heat-resistant quartz crucible and a manufacturing method thereof.The heat-resistant quartz crucible comprises a crucible wall and a crucible bottom which are connected, the crucible wall is divided into an inner layer and an outer layer, the contact face of the inner layer and the outer layer is a continuous fluctuating fusion face, and buckling edges are arranged at top end openings of the inner layer and the outer layer; a compact coating is arranged on the inner wall of the inner layer, mesh ribs are arranged on the outer wall of the outer layer, and the buckling edges and the mesh ribs are connected with the crucible wall through laser melting; the method comprises the steps that a first sand layer is injected into a graphite die sleeve, a second sand layer and a third sand layer are injected between a die core and a spacer ring/between the spacer ring and the graphite die sleeve, a pressing ring is driven to press downwards, and high-temperature fused quartz flow is jetted along a mesh rib groove, a buckling edge and a crucible wall joint; through the spacer ring process, the use amount of high-purity quartz sand is reduced, the high-purity quartz sand and the low-purity quartz sand are accurately fed, the thickness of the crucible is accurate and uniform, and impurities are prevented from entering the crucible; the wall and the opening edge of the quartz crucible are effectively prevented from collapsing and recessing; and the chamfering process of the crucible body is omitted.
本发明涉及石英坩埚生产技术领域，具体涉及一种耐热石英坩埚及其制造方法，包括相连的坩埚壁和坩埚底，所述坩埚壁分为内层和外层，所述内层和外层接触面为连续起伏状融合面，两者顶端口设置有扣边，所述内层的内壁设置有致密涂层，外层的外壁设置有网筋，扣边和网筋通过激光熔融与坩埚壁相连；方法包含将第一砂层注入石墨模套中，第二砂层/第三砂层分别注入模芯和隔环之间/隔环和石墨模套之间，驱动压环下压，沿网状筋槽、扣边和坩埚壁接缝喷射高温熔融石英流；本发明通过隔环工艺，减少了高纯度石英砂的用量，高、低纯度石英砂投放精确，坩埚的厚度精准均匀，也避免携带杂质进入；有效防止石英坩埚壁和口边软塌内凹；免去坩埚本体的倒棱工序。
