Introduction:Graphite crucibles, can be used in the sintering process of positive and negative electrode materials in the lithium battery industry. They are mainly used as powder-carrying containers. Which heated in a furnace and used under the protection of inert gas, so that service life will be longer. Generally, customized bottom plates and cover plates are provided according to the type of kiln. In recent years, graphite saggers have been widely used by high-temperature furnace companies and lithium iron phosphate companies.It is a box-shaped graphite product precisely processed from high-purity graphite. It is used for sintering lithium iron carbonate materials in lithium batteries. It is mainly used as a container for negative accumulation powder and is placed in a graphitization furnace to heat the negative electrode material to achieve graphitization and purification. It is also commonly known as lithium iron phosphate graphite sagger and graphite sagger.
Features:Reasonable design, high purity, good air permeability, and fast evaporation of impurities.
High purity, excellent mechanical properties, strong temperature and corrosion resistance, excellent antioxidant properties, long service life, and high overall cost performance;
Application::Mainly used for smelting metals and various non-metallic substances, such as lithium battery materials, lithium iron phosphate materials, or graphite saggers for sintering magnetic materials.
Graphite sagger is a container used for graphitization of lithium battery negative electrode materials.
