Amorphous Graphite

Amorphous graphite, also known as aphanitic graphite, microcrystalline graphite, or cryptocrystalline graphite, is highly regarded in both domestic and foreign graphite markets. It is often referred to as "gold sand." This type of graphite has a high fixed carbon content, minimal harmful impurities, and very low sulfur and iron content. Its quality places it in the category of high-quality microcrystalline graphite.

Most amorphous graphite samples consist primarily of graphite carbon. They exhibit a rigid ash color, metallic luster, and soft texture. With a Mohs hardness rating of 1-2 and a specific gravity ranging from 2 to 2.24, amorphous graphite is chemically stable and unaffected by strong acids and alkalis. Notably, it contains low levels of iron, sulfur, phosphorus, nitrogen, molybdenum, and hydrogen.

Based on its output form, amorphous graphite can be classified into two types: dispersed amorphous graphite ore and dense massive amorphous graphite ore. These distinctions are essential for understanding its various applications and properties.

Carbon content（%）	Ash（%）	S(%)	P(%)	Moisture(≤%（%）	Size(mesh)（目）
≥70	≤26	≤1	microscale	≤2	100-300
≥80	≤13.5	≤0.8	microscale	≤2	100-300
≥85	≤12	≤0.7	microscale	≤2	100-300
≥90	≤6	≤0.6	microscale	≤2	100-300

1. Casting Coating:
   - Amorphous graphite is commonly used as a coating material for casting molds. Its lubricating properties help prevent sticking and improve the surface finish of castings.

2. Oil Field Drilling:
   - In the oil and gas industry, amorphous graphite serves as an additive in drilling fluids. It enhances lubrication, reduces friction, and stabilizes wellbores during drilling operations.

   - Amorphous graphite is a key component in battery carbon rods. These rods are used in dry cell batteries, providing electrical conductivity and stability.

4. Steel Production:
   - As a carbon source, amorphous graphite contributes to steelmaking. It acts as a carburizing agent, enhancing the hardness and strength of steel.

5. Refractory Materials:
   - Refractories, which withstand high temperatures, often contain amorphous graphite. These materials are used in furnaces, kilns, and other heat-intensive applications.

6. Dyes and Pigments:
   - Amorphous graphite serves as a black pigment in dyes, paints, and coatings. Its dark color adds depth and opacity to various products.

7. Electrode Paste:
   - Electrode paste, used in electric arc furnaces, contains amorphous graphite. It facilitates electrical conductivity during metal smelting processes.

8. Writing Instruments:
   - Amorphous graphite is the primary material in pencil leads. Its softness allows for smooth writing and easy erasing.

9. Graphite Emulsion:
   - Graphite emulsions, used as lubricants and coatings, often incorporate amorphous graphite. They provide excellent anti-friction properties.

10. Desulfurization Agent:
    - In steelmaking, amorphous graphite aids in desulfurization by capturing sulfur impurities during the refining process.

11. Preservative Antiskid Agent:
    - Amorphous graphite is added to road paints and coatings to improve skid resistance and durability.

12. Protective Slag Smelting Carburant:
    - During metal smelting, protective slag contains amorphous graphite as a carburizing agent.

13. Graphite Bearing Products:
    - Bearings and bushings often incorporate amorphous graphite due to its self-lubricating properties.
