China- Quarry locates in the mountainous areas of the southwest China, the mines of our company are abundant in superior natural stone resources, amount which there is one kind called Nyx black marble under exploitation. This Nyx black marble is a kind of stone without odor, toxin and radiation.
This kind of stone is in possession of excellent physical properties and strong adaptability. In addition, it is widely applied in different fields. It is best applied to the environment with high strength and variable climate.
This kind of stone has lots of good characteristics, as followings: good uniformity of the structure, fine and dense texture, low porosity and water absorption, high compressive, flexural and shearing strength, small variation in strength under both the dry and wet circumstance, high hardness, extremely small variation in physical properties, good stability and so on.
This kind of stone is highly polished and as shiny as a mirror. Its glossiness is well above the demand of our country??s first class glossiness of the key marbles.
The data of each physical inspection of this stone complies with or even excels the industrial standards related to marbles which are constituted by the Geological and Mining Department, and also accords to Standard GB/T18600-2001. Unquestionably, this kind of stone belongs to the Class A stone in China.
Description of the Physical Index of the Mine: Natural capacity is 3.3g/cm3; Calcite content amounts to about 93%; It is free of metallic minerals; Saturated water absorption is 0.155%; Porosity is 0.412%; Flexural strength is 172kg/cm3; Dry compressive strength is 1052kg/cm2; Scratch hardness is from 3.6 to 3.8; Wear resistance is 17.79g/cm2; and glossiness is 119 degrees
