Our precision-engineered Quartz Boats are designed to meet the rigorous requirements of semiconductor and chemical processing applications. Crafted from ultra-pure fused quartz (SiO₂), these boats provide a stable and contamination-free environment for silicon wafers, substrates, and other delicate materials during high-temperature operations such as diffusion, oxidation, and chemical vapor deposition (CVD). Quartz’s superior thermal stability, chemical resistance, and minimal thermal expansion make it an ideal choice for cleanroom environments and high-performance manufacturing processes.



We offer a wide range of over 50 standard and custom quartz boat designs to suit diverse process needs. Customization options include specific dimensions, slot configurations, and hook placements for ease of use. Additionally, we provide repair services, including fire repair, to prolong the service life of your quartz components.
