Physical Properties of Anthracite

Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Anthracite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Anthracite rock are vital in determining its Anthracite Texture and Anthracite Uses.

Hardness and Strength of Anthracite

The physical properties of Anthracite depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Anthracite is 1-1.5 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Anthracite is black whereas its fracture is conchoidal. Luster of Anthracite is the interaction of light with the surface of Anthracite. Luster of Anthracite is shiny. Anthracite cleavage is non-existent. The specific gravity of Anthracite is 1.1-1.4. Anthracite is opaque in nature whereas its toughness is not available. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks.
