Silicon carbide crucible with thermal shock resistance and manufacturing technology of silicon carbide crucible
The invention belongs to the field of crucible manufacturing, and particularly relates to a silicon carbide crucible with thermal shock resistance and a manufacturing technology of the silicon carbide crucible in order to solve the technical problem that a silicon carbide crucible manufactured with a conventional method is easy to break under quick cooling and quick heating conditions due to high sintering cost, high thermal expansion coefficient, small elasticity and poor thermal shock resistance. According to the technical scheme for solving the technical problem, the silicon carbide crucible with the thermal shock resistance and the manufacturing technology of the silicon carbide crucible are provided. The silicon carbide crucible with the thermal shock resistance comprises components in percentage by mass as follows: 75%-85% of silicon carbide, 7%-17% of a deoxidant, 0.7%-1% of an additive, 2%-7% of a binder and the balance of a release agent. The silicon carbide crucible with the thermal shock resistance has excellent thermal shock resistance and cannot burst when fed into or discharged out of a furnace hearth at the temperature higher than or equal to 1,200 DEG C, and meanwhile, the manufacturing technology of the silicon carbide crucible with the thermal shock resistance is simple and easy and has the potential for mass production.
