Graphite powder price

The price of graphite powder is affected by a variety of factors. The most important of which is the purity and particle size of graphite powder. In general, the higher the purity of graphite powder, the higher the price. For example, the purity of 95% of graphite powder, the market price is about 300-500 USD per ton. The purity of more than 99% of the high-purity graphite powder, the price may be as high as 1000-2000 USD per ton.

Particle size is also a key factor affecting the price, the smaller the particle size. And the more difficult the preparation, the higher the price. D50 is 50μm graphite powder, if the price is about 580 USD per ton, D50 is 10μm graphite powder price is 780-850 USD per ton. Other common types, such as flake graphite 1um, 60 USD/kg. High purity fine graphite powder 800 mesh, 18 USD/kg. Expanded flake graphite, 1.2 USD/kg. Lubricating graphite powder, 3.8 USD/kg.

In addition, the origin and market supply and demand of graphite powder will also have an impact on the price. The quality of graphite ores from different places is different, and the quality and price of graphite powder produced are also different. When the market demand is strong, and the supply is relatively insufficient, the price of graphite powder will rise. On the other hand, if the market is oversupplied, the price will fall.

What to look for when buying graphite powder?

Clear requirements

Before purchasing it, it is necessary to clarify your own use needs. Different application scenarios have different performance requirements for graphite powder. If used for battery electrode manufacturing, it is necessary to select high-purity, fine-grained graphite powder to ensure the performance and capacity of the battery. If used for ordinary lubrication purposes, the requirements for purity and particle size are relatively low. And you can select the more affordable products. Also you should consider the amount of it, according to the actual demand to determine the amount of procurement. To avoid excessive procurement caused by the backlog of funds and inventory waste, or purchase too little affect the production schedule.

Product quality

Product quality is the key to purchasing it. You should pay attention to the purity of graphite powder, particle size distribution, moisture content and other indicators. You can ask the supplier to provide a test report of the product to see if it meets the relevant standards. For some applications with high quality requirements, such as the electronics field, it is recommended to choose products with quality certification. Such as ISO quality system certification. To ensure the stability and reliability of product quality.
