Silicon carbide (SiC) ceramics, known for their high strength, hardness, wear resistance, corrosion resistance, and high-temperature stability, have demonstrated immense potential and value across numerous industrial sectors since their introduction.

The thermal conductivity of bulk 3C-SiC, recently measured, is the second-highest among inch-scale large crystals, ranking just below diamond. Silicon carbide (SiC) is a wide bandgap semiconductor extensively used in electronic applications, and it exists in various crystalline forms known as polytypes. Managing high localized heat flux is a significant challenge in power electronics, as it can lead to device overheating and long-term performance and reliability issues.

Gallium oxide (Ga2O3) as an "ultra-wide bandgap semiconductor" material has garnered sustained attention. Ultra-wide bandgap semiconductors fall under the category of "fourth-generation semiconductors," and in comparison to third-generation semiconductors such as silicon carbide (SiC) and gallium nitride (GaN), gallium oxide boasts a bandgap width of 4.9eV, surpassing silicon carbide's 3.2eV and gallium nitride's 3.39eV. A wider bandgap implies that electrons require more energy to transition from the valence band to the conduction band, endowing gallium oxide with characteristics like high voltage resistance, high-temperature tolerance, high power capability, and radiation resistance.

According to the research results, TaC coating can act as a protection and isolation layer to extend graphite component life, improve radial temperature uniformity, maintain SiC sublimation stoichiometry, suppress impurity migration, and reduce energy consumption. Ultimately a TaC-coated graphite crucible set is expected to improve SiC PVT process control and product quality.

By 2027, solar photovoltaic (PV) will overtake coal as the world's largest installed capacity. The cumulative installed capacity of solar PV nearly triples in our forecast, growing by nearly 1,500 gigawatts over this period, and will surpass natural gas by 2026 and coal by 2027.
