Why Choose Jincheng Graphite Boats?
We manufacture precision graphite boats, trays, and sintering fixtures for furnace manufacturers and material processing companies. Our boats are available in standard rectangular designs as well as custom geometries with pockets, dividers, and special shapes to hold your specific products during heat treatment. We also offer CVD SiC coating for applications requiring even higher purity and longer life.
FAQ
Q: Can graphite boats be used in air atmosphere?
A: Graphite boats can be used in air up to approximately 450-500°C before significant oxidation occurs. For higher temperature operation in oxidizing atmospheres, we recommend CVD SiC coating or using alumina or quartz fixtures instead.
Q: How long do graphite boats last in production?
A: Boat life depends on operating temperature, atmosphere, loading, and thermal cycling frequency. In controlled atmosphere or vacuum furnaces, graphite boats can last for hundreds of cycles. Regular inspection and careful handling will maximize service life.
Q: Can you design custom boat shapes for my products?
A: Yes, we specialize in custom graphite fixtures. Please provide information about your product dimensions, furnace size, and process requirements, and our engineering team will design optimal boat geometries for your specific heat treatment application.
