Sandblasted Boat

product details

The solar photovoltaic fused silica boat is designed to support silicon wafers during key high-temperature steps in solar cell manufacturing, such as diffusion, oxidation, and annealing. Made from ultra-pure fused silica, it ensures minimal contamination and excellent thermal stability throughout repeated process cycles.

Its precise structure maintains consistent wafer spacing, promoting uniform gas flow and controlled thermal distribution—both essential for achieving high cell efficiency and yield. The material’s superior resistance to thermal shock and chemical attack makes it a dependable choice for aggressive furnace environments in PV production lines.
