Aluminum oxide ceramic automotive sensors, brake discs, battery separators, battery negative electrode materials
With the continuous development of the automotive industry and the increasing demand for environmental protection, energy conservation, safety, and comfort from people, the materials used in automobiles are also constantly changing. Especially under the wave of electrification, the system design of automobiles has undergone earth shaking changes, and advanced ceramic materials are slowly emerging in the application of new energy vehicle parts.
Advanced ceramic materials are composed of ionic or covalent bonds, thus possessing excellent properties such as high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance, and good biocompatibility. However, due to the fact that ceramic powders are mostly ionic or covalent bonding compounds, the traditional sintering process requires a higher sintering temperature and longer insulation time to prepare dense ceramic materials, which inevitably leads to grain coarsening and residual pores, thereby affecting the various properties of ceramic materials. To solve such problems, sintering is the most important step.
At present, how to achieve rapid densification of materials at lower sintering temperatures and prepare ceramic blocks with completely no pores, uniform structure, small grains, and strengthened grain boundaries is still a continuous goal pursued by ceramic material scientists. The innovation of ceramic sintering equipment and sintering technology is the most crucial factor in further improving the performance of advanced ceramic materials.
