Anthracite Properties

Anthracite properties are essential when it comes to identification of rocks. The study of properties of Anthracite rock is done by Mineralogists to determine the identity of rock. Some of the properties of Anthracite include: Hardness, Color, Fracture, Luster, Compressive Strength etc. Anthracite is Medium to Fine Coarse Grained. As compared to other rocks, Anthracite is more porous and its density is 1.25-2.5 g/cm3. Get to know more about physical properties of Anthracite and thermal properties of Anthracite.

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.

Thermal properties of Anthracite

Check out more about What Is Anthracite and its thermal properties. Thermal properties of Anthracite play an important role in geology. Specific heat capacity, resistance offered by the rock to heat, water, pressure etc. are some of the thermal properties of Anthracite.

Specific Heat Capacity of Anthracite

Specific heat capacity is defined as the heat capacity per unit mass of rock. Specific heat capacity or specific heat is one of the important properties of Anthracite. The specific heat capacity of Anthracite is 1.32 kJ/Kg K. Properties of Anthracite also include resistance of Anthracite to heat, water, pressure, impact etc. It helps in determining the parameters to which Anthracite offers resistance. If we talk about Anthracite resistance, Anthracite is heat resistant, water resistant.
