Silicon nitride is an ideal substrate material due to its high heat dissipation capabilities. Among many lattice defects, lattice oxygen is one of the primary defects affecting the thermal conductivity of silicon nitride ceramics. As a result, in order to produce silicon nitride substrates with high thermal conductivity, the lattice oxygen content should be reduced.

In the synthesis of refractory materials, the self-propagating combustion method has the advantages of short synthesis time, low energy consumption, and high product purity. During the self-propagating combustion synthesis of aluminum nitride, the heat emitted by the combustion of aluminum powder during the nitriding reaction serves to keep the reaction process going on spontaneously, so as to obtain AlN powder with high purity.

The advancement of electronic ceramics is essential to the miniaturization and high integration of electronic components. In addition to having excellent electrical properties like high insulation, low dielectric loss, and stable electrical properties, alumina ceramics also have high strength, heat resistance, thermal shock resistance, corrosion resistance, and other properties of ceramic materials. Alumina raw material resources are also plentiful. As a result of its abundant supply, reasonable cost, and well-developed manufacturing process, it finds widespread applications in multilayer wiring ceramic substrates, electronic packaging, and high-density packaging substrates.

For the LED field, alumina transparent ceramics are the most promising alternatives for sapphire (that is, single crystal alumina), which can satisfy the performance requirements of LED packaging substrates that emit light in all directions.

The zirconia back plate is not only attractive, but also scratch-resistant, wear-resistant, and corrosion-resistant, allowing it to meet the requirements of wireless charging. This article describes a new process for preparing zirconia ceramic wireless charging mobile phone back plate in which the wireless charging coil is positioned between the laminated ceramic sheets, avoiding oxidation of the coil when it comes into contact with air and saving internal space.
