High-temperature-resistant high-stability crucible

The utility model discloses a high-temperature-resistant high-stability crucible, relates to the technical field of crucibles, and aims to solve the problems that the existing crucibles are limited mostly by virtue of friction force and size of outer walls when being clamped, and the existing crucibles are toppled over due to insufficient clamping force when being inclined, so that the stability is poor. A charging cavity is formed in the crucible main body, the upper end of the charging cavity is in an opening form, and a crucible cover is arranged at the upper end of the crucible main body; the outer ring clamping seat is arranged on the outer wall of the crucible body, the outer ring clamping seat and the crucible body are of an integrated structure, a clamping inner groove is formed in the outer wall of the outer ring clamping seat, and the clamping inner groove and the outer ring clamping seat are of an integrated structure; the stabilizing frames are arranged on the four faces of the lower end of the cr
