Natural flake graphite is a mineral that is formed through long-term geological metamorphism of carbonaceous rocks. It is a kind of natural crystalline graphite with a fish scale like appearance and presents a layered structure. Natural flake graphite has excellent high temperature resistance, corrosion resistance, thermal shock resistance, radiation resistance, high strength, good toughness, lubrication, plasticity, as well as electrical and thermal conductivity. It is commonly used to make refractory materials, electrode materials for lithium batteries, bipolar plates for fuel cells, brake pads, casting coatings, lubricants, etc. typically appears as fibrous or needle-like crystalline aggregate.
According to the fixed carbon content by mass, natural flake graphite can be divided into four categories: high purity graphite (≥ 99.99%), high carbon graphite (94.00%–99.00%), medium carbon graphite (80%–93%), and low carbon graphite (50%–75%). The technical specifications and main uses of each type of natural flake graphite are shown in the table below.

Expandable graphite, also known as graphite acid, acidized graphite or graphite oxide, is a graphite interlayer compound prepared by using chemical oxidation (chemical method), electrochemical method, microwave method, explosion method and gas phase volatilization method for natural flake graphite treatment. After special treatment, expandable graphite can be instantly expanded into worm-like shape under high temperature.
Different types of insert lead to different intercalation structures, giving it unique physical and chemical properties such as high electrical and thermal conductivity, superconductivity, magnetic permeability, battery performance, catalytic properties, and expansion performance. The application of expandable graphite covers the practical use in high-conductivity materials, battery materials, efficient catalysts, hydrogen storage materials, and improvements in expansible graphite sealing materials.
According to the sulphur content after expansion, expandable graphite is divided into sulfurous expandable graphite (≥ 0.120%) and low sulfur expandable graphite (< 0.120%). The specific properties of expandable graphite is shown in the table below.
Category | Before Expansion | After Expansion | |||||
---|---|---|---|---|---|---|---|
Moisture | pH Value | Weight of Screen Residue (150 μm, 180 μm, 300 μm) | Expansion Volume (mL/g) | Sulfur Content | Fixed Carbon Content | ||
Sulfurous expansible graphite | < 1.00% | 3.00–9.00 | ≤ 20.00% | 50–400 | ≥ 0.120% | 90% – 99% | |
Low sulfur expandable graphite | < 0.120% | ||||||

Micro powder graphite inherits the good properties of natural flake graphite and has special oxidation resistance, self-lubricity and plasticity under high temperatures. Besides, it also has good electrical conductivity, thermal conductivity and adhesion. It is widely used as a release lubricant in the production of catalyst for the fertilizer industry, a high-temperature lubricant base, a corrosion-resistant lubricant base, powder metallurgy release lubricant and metal alloy raw material, carbon film resistance making, conductive dry film and preparation of conductive liquid, plastic, rubber and various composite fillers or performance improvement agent to enhance the wear resistance, electrical resistance or conductivity of materials.
The technical indicator of micro powder graphite is shown in table below.

Graphite emulsion is a emulsion that is mainly composed of micro powder graphite. It features high temperature lubricity, adhesion, easy demolding, stable chemical properties, non-corrosive, non-toxic, enhanced molding quality, significantly extended the service life of the die, etc. Strictly speaking, it should be called as graphite colloid and is divided into forging graphite emulsion, solvent-based graphite emulsion, and water-based graphite emulsion.
Of which, forging graphite emulsion is made from high purity, ultra-fine, natural flake graphite powder obtained by taking high carbon graphite as the raw material and then going through ultra-fine grinding. It is a highly dispersed colloidal graphite emulsion made by taking water as a carrier and then adding appropriate amount of chemical additives such as suspension dispersant, emulsifier, stabilizer, and colloid protectants. This emulsion is an ideal high-temperature release agent for ferrous and non-ferrous black hot working and is widely used in forging and metal forming industries.
