Earthy Graphite
Description:
Earthy graphite also known as micro crystalline graphite,also called amorphous graphite or aphanitic graphite (also known as black lead powder). Generally it's crystal is less than 1 micron in diameter, and only can be seen through the electron microscope.
Features:
Earthy graphite has the properties as gray color, metallic luster, soft, Mohs hardness of 1-2, the proportion of 2-2.24 and chemically stable, free from strong acid-base effect. It has less harmful impurities and with less iron, sulfur, phosphorus, nitrogen, molybdenum and hydrogen. Besides it can resist high temperature, corrosion, acid and antioxidant, meanwhile having good plasticity, lubrication, thermal conductivity and electrical conductivity.
Application:
Earthy graphite is being widely used in casting, painting, batteries, carbon products, pencils, paint, welding rod, graphite emulsion, desulfurization agents, preservatives, lubricants, refining carburant, destined flux and all kinds of refractory materials.
