Intermediate carbon graphite from Yantai Langyu is a medium-carbon material classified under the LZ grade, with a carbon content of approximately 85%. Supplied in particle sizes ranging from 45 to 500 microns (325 mesh to 32 mesh), this graphite is primarily used as a carbon raiser and inoculation agent in steelmaking and foundry applications. Its flake crystal structure is complete and thin, offering good toughness and a range of physical and chemical properties suitable for high-temperature environments.
The material exhibits excellent high-temperature resistance, self-lubrication, electrical conductivity, and thermal shock resistance, making it ideal for refractory applications. It is commonly used in the production of magnesia carbon bricks, crucibles, and other high-grade refractory materials, as well as in military, smelting, and electrical industries. The graphite’s properties also support its use in deep-processing applications, such as graphite emulsions for lubricants, release agents, and conductive coatings.
This grade of graphite is traded globally in bulk quantities, primarily for metallurgical and refractory uses. It is a critical input for industries requiring precise carbon control in molten metal, such as steel mills and foundries. Buyers should confirm the carbon content and particle size distribution to ensure it meets their specific process requirements, as variations can impact performance in high-temperature applications.

Before placing an order, verify the carbon content and particle size distribution of the graphite to ensure it aligns with your production requirements. Request a certificate of analysis (COA) from the supplier, as variations in these parameters can significantly impact performance in steelmaking or refractory applications. Additionally, confirm that the material has been processed to remove excess moisture and volatile matter, which can affect its stability during use.
Discuss packaging options with the supplier, as graphite is typically shipped in bulk bags or drums to prevent contamination and moisture absorption. Clarify lead times, as production and processing may take several weeks, and agree on Incoterms to define responsibilities for shipping, insurance, and customs. Payment terms should be negotiated based on the order volume, with consideration for letters of credit or advance payments to secure supply.
For quality checks, perform random sampling and testing of the graphite upon receipt to verify carbon content, particle size, and moisture levels. Use calibrated laboratory equipment to ensure accuracy, and compare results against the supplier’s COA. If the graphite is destined for refractory applications, test its thermal shock resistance and mechanical strength under simulated operating conditions. Finally, ensure the supplier provides an MSDS and any required compliance documentation for your industry.
