As of the end of 1996, China has identified 222 molybdenum mining areas, distributed in 29 provinces, autonomous regions and municipalities. Molybdenum reserves reach 8.4200 million tons, of which A + B + C grade accounts for 39.8% of the reserves, which is 3.345 [...]
Rare earth oxides are widely used in magnetic materials, catalytic materials, hydrogen storage materials, optical glass, optical fiber and ceramic capacitors. Dysprosium oxide has excellent physical and chemical properties and is used as raw material for dysprosium metal, glass, additive for NdFeB permanent magnets, [...]
Cesium carbonate is an inorganic compound. White solid at room temperature and pressure. It is soluble in water and absorbs moisture quickly when exposed to air. Cesium carbonate aqueous solution is strongly alkaline and can react with acid to form the corresponding cesium salt [...]
Lignin is the only large-scale renewable source of aromatic compounds, and has the advantages of being inedible, widely available and cheap. A wide range of aromatic aldehydes, acids and esters can be obtained by directional catalytic oxygenation of polylignin. Catalysts are the key to [...]
The dispersal of pigment
The dispersing process of pigment consists of three steps: wetting, dispersing and stabilizing. During wetting, the air and water vapor on the pigment surface are replaced by the resin solution, and the solid/gas phase (pigment/air) is converted into the solid/liquid phase [...]
