Crucible and preparation method thereof
The invention provides a crucible and a preparation method thereof, and relates to the technical field of silicon rod preparation, the method comprises the following steps: providing a crucible base body of a first type material, and performing surface treatment on the inner wall surface of the crucible base body to obtain a to-be-bonded area; providing an initial coating raw material of a second type material, wherein the phase of the initial coating raw material comprises solid particles; performing homogenization treatment on the initial coating raw material to obtain a target coating raw material; the average particle size of the target coating raw material is smaller than that of the initial coating raw material; the target coating raw materials are fused through the fusion spraying technology, and the to-be-combined area is coated with the fused target coating raw materials; and cooling the target coating raw material to form the compact crucible coating which is in a metallurgical bonding state with the to-be-bonded area. The compact coating of the crucible has good high temperature resistance and stability, and effectively avoids stripping or falling at high temperature, so that the stability of the compact coating is favorably maintained, and the durability and the stability of the crucible are further improved.
本申请提供一种坩埚及其制备方法,涉及硅棒制备技术领域,该方法包括:提供第一型材质的坩埚基体,并对坩埚基体的内壁面进行表面化处理,以获得待结合区域;提供第二型材质的初始涂层原料,初始涂层原料的物相包括固体颗粒;对初始涂层原料执行均一化处理,以获得目标涂层原料;目标涂层原料的平均粒径小于初始涂层原料的平均粒径;采用熔融喷涂工艺将目标涂层原料熔融、涂覆至待结合区域;冷却目标涂层原料,以形成与待结合区域呈冶金结合态的坩埚致密涂层。这种坩埚致密涂层具有良好的耐高温性能和稳定性,有效避免于高温下发生剥离或脱落的情况,从而有利于维持自身的稳定,进而提高坩埚的耐用性及稳定性。
