With the theme of "How to achieve high quality crystal growth? - SiC crystal growth furnace", this blog conducts a detailed analysis from four dimensions: the basic principle of silicon carbide crystal growth furnace, the structure of the silicon carbide crystal growth furnace, technical difficulties of silicon carbide crystal growth furnace, and raw materials for growing high-quality SiC crystals.

The four most powerful graphite manufacturers in the world: SGL, Toyo Tanso, Tokai Carbon, Mersen and their corresponding typical graphite and application areas.

The article describes the excellent physical properties of Carbon felt, the specific reasons for choosing SiC coating, and the method and principle of SiC coating on carbon felt. It also specifically analyzes the use of D8 ADVANCE X-ray diffractometer (XRD) to analyze the phase composition of SiC coating carbon felt.

The main methods for growing SiC single crystals are: physical vapor transport (PVT), high temperature chemical vapor deposition (HTCVD) and high temperature solution growth (HTSG).

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.

The article analyzes the specific challenges faced by the CVD TaC coating process for SiC single crystal growth during semiconductor processing, such as material source and purity control, process parameter optimization, coating adhesion, equipment maintenance and process stability, environmental protection and cost control, as well as the corresponding industry solutions.
