Slate Stone - Fine-grained Metamorphic Rock, Shades Of Gray, Purple, Green, Fireproof And Thermal Stable

Our
long market research and study help us to offer the best quality
Slate Stone. This mineral is fine-grained, foliated,
homogeneous metamorphic rock that is composed of clay or volcanic ash
through low grade regional metamorphism. Available in various colors
such as shades of gray from pale to dark as well as purple, green or
cyan, this mineral is widely used for interior and exterior flooring,
walkways, stairs, and wall cladding. Some attributes of this Slate
Stone are as follows:

• High
  thermal stability
• Fire
  proof
• Electrical
  insulator

Other Details:

Chemical composition:

Slate is mainly composed of quartz and muscovite or illite, often along with biotite, chlorite, hematite, and pyrite and, less frequently, apatite, graphite, kaolin, magnetite, tourmaline, or zircon as well as feldspar

Uses :

Tiles are installed and set on mortar and grouted along the edges Slate flooring can however be slippery when used in external locations subject to rain.

As it is a good electrical insulator and fireproof, it was used to construct electric switchboards and relay controls for large electric motors. Fine slate can also be used as a whetstone to hone knives.

Due to its thermal stability and chemical inertness, slate has been used for laboratory bench tops and for billiard table tops.

Slate of fine quality is used for gravestones and commemorative tablets and to create statues
