Product Description

Product Introduction

Graphite powder, derived from graphite, an allotrope of carbon, features a layered crystal structure where strong covalent bonds bind carbon atoms within each layer and weak van der Waals forces hold the layers together. It can be produced via mechanical grinding, which crushes natural graphite ore into powder using devices like ball mills and is ideal for lower - purity needs, or through Chemical Vapor Deposition (CVD) to create high - purity artificial graphite powder by decomposing carbon - containing gases and depositing carbon atoms on a substrate. Graphite powder presents as a black or dark - gray powder with a metallic sheen, and its physical properties, including excellent lubricity from layer slippage, low density, and high electrical conductivity, vary based on particle size. Chemically, it remains stable at room temperature, resisting most acids, alkalis, and organic solvents, but reacts with strong oxidants under high - temperature conditions.

Product Application

1. In the Battery Industry

• Lithium - ion Batteries: Graphite powder is widely used as the anode material in lithium - ion batteries. Its layered structure allows lithium ions to intercalate and de - intercalate easily, which is crucial for the charge and discharge process of the battery. High - purity artificial graphite powder is preferred for high - performance lithium - ion batteries used in electric vehicles and consumer electronics, as it can provide higher energy density and longer cycle life.

2. In Lubrication

• Dry Lubricants: Graphite powder can be used as a dry lubricant in applications where traditional liquid lubricants are not suitable, such as in high - temperature environments or in vacuum conditions. It can reduce friction between mechanical parts, extend the service life of equipment, and is often used in the manufacturing of locks, bearings, and sliding components. Additionally, it can be added to lubricating oils and greases to enhance their lubricating performance.

3. In the Foundry Industry

• Mold Release Agent: Graphite powder is applied as a mold release agent in foundries. When metal is poured into molds, the graphite powder forms a thin film on the mold surface, preventing the metal from sticking to the mold. This helps to improve the quality of castings, making it easier to remove the cast parts from the mold and reducing the occurrence of defects such as surface roughness and sticking.

4. In the Production of Refractory Materials

• Refractory Bricks and Linings: Graphite powder is added to refractory materials to improve their thermal shock resistance, thermal conductivity, and mechanical strength. Refractory products containing graphite powder are widely used in high - temperature furnaces, such as blast furnaces, electric arc furnaces, and glass - melting furnaces, to protect the furnace walls from high - temperature erosion.

5. In the Production of Conductive Materials

• Conductive Coatings and Inks: Graphite powder can be used to prepare conductive coatings and inks. These are applied on various substrates, such as plastics, papers, and metals, to endow them with electrical conductivity. For example, in the production of electromagnetic shielding materials, conductive graphite - based coatings can be used to block electromagnetic interference. It is also used in printed circuit boards (PCBs) for making conductive tracks.

6. In the Pencil Industry

• Pencil Lead: Graphite powder is a key component of pencil lead. When mixed with clay in appropriate proportions, it can adjust the hardness and darkness of the pencil marks. Different ratios of graphite to clay result in pencils with different grades, such as 2B, HB, and 2H.
