Physical Properties of Lignite

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

Hardness and Strength of Lignite

The physical properties of Lignite 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 Lignite is 1 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Lignite is black whereas its fracture is conchoidal. Luster of Lignite is the interaction of light with the surface of Lignite. Luster of Lignite is dull to vitreous to submetallic. Lignite cleavage is non-existent. The specific gravity of Lignite is 1.1-1.4. Lignite 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.
