Quartz boat is a kind of high temperature consumables commonly used in semiconductor technology, solar photovoltaic industry, LED, sapphire and other industries. It is mainly used to hold solid materials (powder, granules, blocks) and placed in a high temperature furnace for heating. It has the characteristics of high purity, strong temperature resistance, precise size, smooth surface, easy cleaning, etc. Quartz boat is mainly used in diffusion, annealing, oxidation, chemical vapor deposition (CVD) and other processes in these industries. It can carry and protect the processed materials and ensure the stability and reliability of the process.
