Applications
suitable for key load-bearing components of photovoltaic cell diffusion process equipment.
Advantages
Reaction sintered silicon carbide boat supports/brackets/jigs has stable structure, good thermal stability performance of materials, no deformation during high temperature use, and a long service life, effectively solving the problem of bearing component loss under high load capacity of photovoltaic cells.
Quartz boat supports and boats commonly used in the photovoltaic industry have a service life of 3-6 months due to their production process and quartz material characteristics. Silicon carbide boat supports and boats, which replace quartz, can have a service life of more than 5 years, significantly reducing usage costs and capacity losses caused by maintenance and downtime.
