The invention relates to the technical field of moissanite production, in particular to a crucible for producing colorless moissanite and a method for producing the colorless moissanite, the crucible comprises a crucible main body and a crucible cover, a cavity is formed in the crucible main body, and the crucible cover is arranged in the cavity; the cavity sequentially comprises a powder source area used for containing a silicon carbide powder source and a free flowing area used for conveying silicon carbide gas from bottom to top, a filter layer is arranged above the powder source area, and the filter layer is filled with an adsorbent used for adsorbing impurity gas in silicon carbide sublimation gas flowing out of the powder source area. A heat preservation assembly surrounding the inner wall of the crucible body by a circle is further arranged in the free flowing area, and a seed crystal graphite set used for bonding seed crystals is arranged below the crucible cover. The filter layer filled with the adsorbent is arranged in the crucible main body, so that small-particle impurities and impurity gas in silicon carbide sublimation gas can be effectively removed, and the problem that moissanite has mixed colors is effectively prevented.
本发明涉及莫桑石生产技术领域，尤其涉及一种用于生产无色莫桑石的坩埚及生产无色莫桑石的方法，所述坩埚包括坩埚主体以及坩埚盖，所述坩埚主体内部设置有一空腔，所述空腔从下至上依次包括用于放置碳化硅粉源的粉源区以及用于输送碳化硅气体的自由流动区，所述粉源区上方设置有一个过滤层，所述过滤层内部填充有用于吸附从粉源区流出的碳化硅升华气中的杂质气体的吸附剂，所述自由流动区内部还设置有环绕坩埚主体内壁一周的保温组件，所述坩埚盖下方设置有一用于粘结籽晶的籽晶石墨组。本申请通过在坩埚主体内部设置有一个填充有吸附剂的过滤层能够有效去除碳化硅升华气中的小颗粒杂质以及杂质气体有效防止莫桑石出现杂色的问题。
