NOVELTY - The method involves performing the pressure-less sintering process, vibration ball milling and stirring and mixing. The centrifugal mixer is adopted by mixing and stirring to perform stirring and mixing. Barium titanate, vanadium trioxide, chromium oxide, boron carbide powder, graphene material, yttrium oxide powder, zirconium dioxide and graphene material are taken out, and pulverized by vibration ball milling. The particles of barium titanate, vanadium trioxide, chromium oxide, boron carbide powder, yttrium oxide powder and zirconium dioxide are taken out, and mixed and stirred by a centrifugal mixer. Anti-aging agent is added after the stirring is completed, and secondary centrifugal stirring is performed to obtain ceramic raw materials. USE - Preparation method of semiconductor ceramic material used in electronic product such as computers, mobile phones, or core units of digital recorders. Uses include but are not limited to integrated circuit, consumer electronics, communication system, photovoltaic power generation, illumination and large power supply conversion field such as diode. ADVANTAGE - The high temperature stability is ensured through boron carbide powder, the use of semiconductor materials is ensured, and temperature detection is ensured through vanadium trioxide and chromium oxide to ensure detection speed. The heat conduction is performed through graphene material to ensure rapid temperature detection. The semiconductor materials are protected using polyolefin to prevent damage. The high temperature expansion is prevented using zirconium dioxide. The appearance color of the semiconductor ceramic is guaranteed by the anti-aging agent, and the aesthetics is guaranteed.
