The so-called basalt refers to a kind of stone. Natural Basalt Stone Tile has the advantages of wear resistance, low draught, poor electrical conductivity, strong compression resistance, low crush value, strong corrosion resistance, and asphalt adhesion. It is internationally recognized. It is the best cornerstone for the development of railway transportation and road transportation. The main components of basalt are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, and magnesium oxide (as well as a small amount of potassium oxide and sodium oxide), of which the silicon dioxide content is the largest, accounting for about 45 percent to Fifty or so.

The colors of basalts are mostly black, dark brown or dark green; the basalts near the Tengchong volcanic group are mostly blue-gray, and there are also dark red, orange and yellow. Because of its dense texture, its specific gravity is heavier than that of ordinary granite, limestone, sandstone, and shale. However, some basalts have a large number of pores, so the weight is reduced, and they can even float in the water. Therefore, this light porous basalt is called "pumice stone". In the village near the foot of the Tengchong Mazhan volcanic group in Yunnan, people call these light porous basalts "foam".


Basalt is a Volcanic Rock. It is the main component of the earth's oceanic crust and the lunar and lunar sea. It is also an important component of the earth's crust and the lunar and lunar land. The relevant minerals are copper, iron, zinc, cobalt, Bingzhou stone and agate. It can be used as a high-quality raw material for casting stone and can be used as an excellent stone. Due to the low viscosity and high fluidity of basalt magma, large-scale lava flows and lava blankets are likely to form on the surface of the basalt, but there are also layered intrusions such as rock beds.


According to the Natural Volcanic Stone Supplier, basalt is widely used, and its application is not limited to the construction industry. For example, basalt is a good raw material for the production of "cast stone". It can be melted and cast, crystallized, and annealed. Forms a new type of alloy steel that is hard and wear-resistant, and is more resistant to corrosion than lead and rubber; basalt can also play the role of "lubricant" in an advanced steel casting process, which can prolong the life of the cast film; and basalt It can also be drawn into glass fiber, and the basalt glass fiber cloth made is stronger in alkali resistance and good in high temperature resistance than general glass fiber cloth. Basalt is the best material for repairing roads, railways, and airport runways. It has strong compressive resistance, low crushing value, strong corrosion resistance, and asphalt adhesion basalt. Basalt has wear resistance and low draught. Poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion resistance, asphalt adhesion and other advantages, and internationally recognized, is the best cornerstone for the development of railway transportation and road transportation.
