In recent years, the application of lanthanide reagents in organic synthesis has been developed by leaps and bounds. Among them, many lanthanide reagents were found to have obvious selective catalysis in the reaction of carbon-carbon bond formation; at the same time, many lanthanide reagents were fo...
The rapid development in the fields of information and optoelectronics has promoted the continuous updating of chemical mechanical polishing (CMP) technology. In addition to equipment and materials, the acquisition of ultra-high-precision surfaces is more dependent on the design and industrial produ...
Colloidal Antimony Pentoxide is an antimony flame retardant product developed by industrialized countries in the late 1970s. Compared with antimony trioxide flame retardant, it has the following application characteristics:
1. The colloidal antimony pentoxide flame retardant has a small amount of sm...
The two largest producers of Antimony Trioxide in the world have ceased production . Industry insiders analyzed that the suspension of production by the two major producers will have a direct impact on the future spot supply of the antimony trioxide market. As a well-known antimony oxide production...
Manganese Dioxide is a black powder with a density of 5.026g/cm3 and a melting point of 390°C. It is insoluble in water and nitric acid. Oxygen is released in hot concentrated H2SO4, and chlorine is released in HCL to form manganous chloride. It reacts with caustic alkali and oxidants. Eutectic,...
The novel coronavirus pneumonia epidemic, medical protective materials such as medical rubber gloves are in short supply. However, the use of rubber is not limited to medical rubber gloves, rubber and us are used in every aspect of people’s daily life.

Boron Carbide is a black crystal with metallic luster, also known as black diamond, which belongs to inorganic non-metallic materials. At present, everyone is familiar with the material of boron carbide, which may be due to the application of bulletproof armor, because it has the lowest density amon...
The element barium is known to be toxic, but its compound barium sulfate can act as a contrast agent for these scans. It has been medically proven that barium ions in salt interfere with the body’s calcium and potassium metabolism, causing problems such as muscle weakness, difficulty breathing...
Background and General Situation
Rare earth elements are the floorboard of IIIB scandium, Yttrium and Lanthanum in the periodic table. There are l7 elements. Rare earth has unique physical and chemical properties and has been widely used in industry, agriculture and other fields. The purit...
Lithium Carbonate and Lithium Hydroxide are both raw materials for batteries, and the price of lithium carbonate has always been some cheaper than lithium hydroxide. What is the difference between the two materials?
Firstly, in production process, both can be extracted from ...
In this intelligent era, we are increasingly inclined to choose smart heat insulation methods.Cs0.33WO3 transparent thermal insulation coating, a kind of thermal insulation materials with certain application prospects, is expected to replace the existence of thermal insulation ma...
The role of Strontium Carbonate in glaze: frit is to pre-smelt the raw material or become a glass body, which is a commonly used flux raw material for ceramic glaze. When pre-smelted into flux, most of the gas can be removed from the glaze raw material, thus reducing the generation of bubbles and sm...
