Molybdenum is a metal element that was discovered relatively recently. Molybdenum metal has the advantages of a high melting point, high strength, good corrosion resistance and good resistance to abrasion. With endogenous ores, molybdenite combines mai
Bentonite is also called porphyry, soapstone or bentonite, the main mineral component is montmorillonite, bentonite some physical and chemical properties are determined by montmorillonite. Bentonite can swell into a paste when water is added, so in gen
Coke is due to bituminous coal in the isolation of air conditions, heated to 950-1050 ℃, after drying, pyrolysis, melting, bonding, curing, contraction and other stages of the final product, the ignition temperature of 450-650 ℃, the porosity of 35
Platinum group metal elements are much more expensive than gold and silver, and are contained in the earth's crust in small quantities and are dispersed, with few concentrated deposits. Platinum group metals include platinum, palladium, rhodium, ir
Bituminous coal is a class of coal. This type of coal contains 75 to 90 per cent carbon and no free humic acids. Most of it is cohesive; the calorific value is high. Density is about 1.2-1.5. volatile matter is about 10-40 per cent. Relative density 1.
Silica CharacteristicsSilica is a general term for vein quartz, quartzite and quartz sandstone. It has a high melting point and boiling point, and is chemically stable, insoluble in water and does not react with water, and does not act with gene
Raw coal refers to the coal extracted from the ground or underground gross coal after screening and processing to remove gangue, pyrite and so on. Unwashed and unprocessed gross coal produced from coal mines is also called raw coal. Coal is mainly comp
Coal dust is a combustible material, particle characteristics of coal dust is composed of size does not pass, irregular shape of the particle powder, general coal dust particle diameter range of 0-1000um, mostly 20-50um particles. The role of coal dust
Lime an air-hard inorganic cementitious material with calcium oxide as the main component. Lime is made of limestone, dolomite, chalk, shells and other products with high calcium carbonate content, calcined at 900 to 1100 degrees Celsius. Lime is the e
Limonite is one of the principal iron minerals, and is of many shades of brown, generally stalactitic, grape-like, dense or loose lumpy or even earthy. As it is a weathering product of iron-bearing minerals, it is impure in composition and highly varia
