Quartz devices play a critical role in solar cell manufacturing, offering exceptional thermal resistance, chemical purity, and structural stability required in high-temperature processes. From quartz diffusion tubes and crucibles to quartz boats and furnace components, these high-purity materials are essential for achieving optimal efficiency in diffusion, CVD, and wet etching steps.

The core material of PECVD graphite boat is high-purity isotropic graphite material (purity is usually ≥99.999%), which has excellent electrical conductivity, thermal conductivity and density. Compared with ordinary graphite boats, PECVD graphite boats have many physical and chemical property advantages and are mainly used in the semiconductor and photovoltaic industries, especially in PECVD and CVD processes.

Porous SiC Ceramic Plate is one of the core materials in the field of semiconductor manufacturing. With its unique structure and excellent physical properties, Porous SiC Ceramic Disc has become an irreplaceable key component in high temperature and corrosive environments. In this article, we will deeply analyze its physical properties, application scenarios and selection advantages.

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.

SiC and GaN are wide bandgap semiconductors with advantages over silicon, such as higher breakdown voltages, faster switching speeds, and superior efficiency. SiC is better for high-voltage, high-power applications due to its higher thermal conductivity, while GaN excels in high-frequency applications thanks to its superior electron mobility.
