Carbon black, also known as carbon black, is an amorphous carbon, light, loose and very fine black powder with a very large surface area ranging from 10-3000m2/g and a specific gravity of 1.8-2.1. It is an indispensable chemical raw material in industr
Dirt, soil, waste materials and other wastes generated during construction or demolition and repair are called construction waste. In the face of large-scale creation and renovation of urbanisation, the total amount of construction waste in China has r
River pebbles are natural green stone, formed through long-term impact of flowing water, handling, sediment deposition, mostly found in ancient river beds. With hard texture and different colours, it can be used for interior decoration, paving, art cre
Slag structureSlag containing more SiO2 is acidic slag and slag containing more Al2O3 and CaO is basic slag. The activity of alkaline slag is higher than that of acidic slag. Slag should not be stored for a long time because it has a certain deg
As China's urbanisation as well as industrialisation continues, the demand for iron and steel volumes will continue to increase, and so will the demand for MnSi alloys. 518.177 million tonnes of crude steel were produced in January-November 2009, a
Shale is formed by the hardening of clay materials into tiny grains that are fissile and easily split into distinct formations. The composition is complex, with papyraceous or lamellar laminations. It splits easily into fragments when struck with a har
Silica sand stone is a hard, wear-resistant, chemically stable silicate minerals, its main mineral composition is SiO2 , silica sand colour is milky white or colourless translucent, hardness 7, brittle and non-dissolving, shell-like fracture, greasy lu
Properties of aluminium hydroxideAluminium hydroxide is the hydroxide of aluminium, which can react with acid to form salt and water as well as with strong alkali to form salt and water, it is a kind of amphoteric hydroxide, white powdery solid,
Zeolite is a mineral that was first discovered in 1756. The Swedish mineralogist Kronsti found that there is a class of natural silicate-aluminium ore will produce boiling phenomenon when burning, so named "zeolite". Since then, people's
Activated carbon is a kind of porous carbon material with highly developed void structure and huge specific surface area, strong adsorption capacity, good chemical stability, high mechanical strength, easy to regenerate after failure, etc. It is widely
