product description

Lab graphite tubes, an seemingly unimportant pipe material, is a key component that determines the success or failure of experiments in scenarios that require extreme temperatures and pure environments.

Carbon graphite tubes made of high-purity graphite materials are important for use as heating elements or furnace tubes in ultra-high experiments. Under vacuum or argon or nitrogen protection, high-purity graphite tubes can withstand high temperatures of around 3000 ℃, far exceeding the limit of most metal heating elements. In tubular graphite furnaces, it is often used as a heating element for high-temperature sintering, graphitization, purification, and carbonization experiments of small batch precision samples. It is a commonly used tool in university laboratories and new material research and development.

In addition, carbon graphite tubes can also be used in the preparation of semiconductor and photovoltaic materials. It and various graphite components are commonly used in high-purity carbon material scenarios related to crystal growth of silicon, silicon carbide, sapphire, etc., and also appear in processes such as epitaxy and etching. During the growth of silicon carbide single crystals and purification of high-purity silicon, graphite components need to maintain structural stability and low pollution under extreme temperatures and corrosive atmospheres. The chemical inertness and high-temperature strength of high-purity graphite tubes perfectly match this requirement.
