Compression molding, isostatic pressing, and rod extrusion are the three most common methods for producing graphite rods, similar to those used for creating graphite tubes.

In the world of high-temperature heating, achieving precision and reliability in extreme conditions is paramount. To meet these challenges, innovative materials and designs have been developed to push the boundaries of what's possible. One such advancement is the Silicon Carbide (SiC) coated graphite heating element.

In the process of growing SiC and AlN single crystals by the physical vapor transport method (PVT), components such as the crucible, seed crystal holder and guide ring play a vital role. During the preparation process of SiC, the seed crystal is located in a relatively low temperature region, while the raw material is in a high temperature region exceeding 2400°C. The raw materials decompose at high temperatures to form SiXCy (including Si, SiC₂, Si₂C and other components).

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.

The ultra-high synthesis temperature and the difficulty of achieving dense sintering of SiC ceramics have limited their development. The sintering process is crucial for SiC ceramics.
