The invention discloses a high-temperature bending resistance detection device for a novel ceramic silicon nitride material. The device comprises a detection box body, a detection cavity is formed inthe detection box body, a ceramic bending device is arranged in the detection cavity, and the ceramic bending device comprises a rotating shaft rotationally connected with the inner wall of the rear side of the detection cavity. Whether the bending strength of silicon nitride ceramic in a high-temperature environment is qualified or not is detected, silicon nitride has strong heat resistance and is often used in a high-temperature environment, and the quality of a workpiece in a high-temperature environment must be detected to ensure the working state and the safety of the workpiece in the high-temperature environment. According to the equipment, one side of the ceramic is clamped, and the other side of the ceramic is pushed, so that silicon nitride is bent and deformed.
Description
technical field [0001] The invention relates to the field of new materials, in particular to a high-temperature anti-bending detection device for a novel ceramic silicon nitride material. Background technique [0002] Silicon nitride ceramics is an inorganic material ceramic that does not shrink during sintering. Silicon nitride has high strength, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, High temperature resistance and other properties. [0003] Si3N4 ceramic is a covalent bond compound, the basic structural unit is a tetrahedron, the silicon atom is located in the center of the tetrahedron, and there are four nitrogen atoms around it, which are respectively located at the four vertices of the tetrahedron, and then every three tetrahedrons In the form of sharing one atom, a continuous and solid network structure is formed in three-dimensional space. [0004] Silicon nitride is generall...
