Crystal ferrocene has a wide range of applications and excellent practical results

Crystal ferrocene is a kind of burning rate catalysts, appearance is orange spicules, ferrocene in the powder and the latest crystalline morphology, crystalline in nature and the powder is the same, but in actual use crystal ferrocene can solve the problem of powder of ferrocene fly powder, reduce the unnecessary loss, and crystalline ferrocene dissolved more thoroughly, the effect is better. Ferrocene is also known as ferrodicyclopentadiene. The boiling point is above 200 degrees Celsius, the melting point is [...]

The scientists obtained highly doped up-conversion nanoparticles

Led by Australia’s Macquarie university professor da-yong jin advanced cell instrument laboratory and engineering college of Beijing university department of biomedical engineering XiPeng research joint research, found the new nano photonics light-emitting mechanism, and implements the high concentration of doping on the conversion of nanoparticles (Upconversionnanocrystals) technology, which shows the most sensitive nano fluorescent material yet. The paper was published in Nature Nanotechnology. Upconversion nanoparticles, a novel fluorescent material, are promising a wide range of applications with their unique optical [...]

How to make hexagonal boron nitride powder

Boron nitride is a new ceramic material with excellent properties and great development potential. Hexagonal boron nitride (h-bn) is an isomer of boron nitride. The structure of hexagonal boron nitride is similar to that of graphite, with a hexagonal layered structure, soft texture, strong workability, and white color, commonly known as “white stone ink”. The following to introduce the commonly used method of making powder of hexagonal boron nitride. 1. Chemical vapor deposition (CVD) method. H-bn powder is generally prepared by [...]

Technology and principle of industrial extraction of vanadium pentoxide

The main raw materials for industrial extraction of vanadium pentoxide are vanadite-containing coal mines and vanadium titanomagnetite. The grade of vanadium pentoxide in vanadite-containing coal mines is generally 0.5-1.5%, and vanadium titanomagnetite is vanadium pentoxide Grade is generally between 1.0 and 5.0%. Mineral decomposition There are two kinds of decomposition methods of vanadium ore, the first is sintering method, the pulverized ore powder mixed with soda ash or sodium salt and sintered at high temperature, so that the low-priced vanadium oxidized and [...]
