We all know that magnesium oxide is active and light, and there is also a kind of light burned powder also called magnesium oxide. However, many people mistakenly believe that light burned powder is light magnesium oxide, but in fact it is not the case. Although the main components of both are MgO, the important difference between light burnt and light weight is that the content is different, the ...

Nano zinc oxide is a new type of high-functional fine inorganic product facing the 21st century. The particle size of nano-zinc oxide produced by SAT NANO is 20-30nm. Due to the miniaturization of particle size and large specific surface area, nano-ZNO produces nano-materials. Surface effects, small size effects and macroscopic quantum tunneling effects are available. The magnetic, optical, electr...

Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted at high temperature in a resistance furnace. The raw materials used in the manufacture of green silicon carbide, such as black silicon carbide, are roughly the same, and industrial salt is added as a reactant and accelerator to react in a resistance furnace. In terms of it...

1. The lubricity of boron nitride Boron nitride came out more than 100 years ago. Its earliest application polymorph is hexagonal boron nitride as a high-temperature lubricant, abbreviated as: h-BN, or a-BN, or g-BN (that is, graphite boron nitride), Hexagonal boron nitride is absolutely smooth, and the friction coefficient between the powders is very low. Each layer of its atomic structure contai...

Cesium Tungsten Bronze (CsxWO3) is a non-stoichiometric functional compound with a special oxygen octahedral structure. It has low resistivity and low temperature superconductivity. In recent years, it has been discovered that CsxWO3 film has good near-infrared shielding performance, which is expected to replace the existing ITO conductive glass. As a window material, it can be used as a good near...

Fullerene is the third allotrope of elemental carbon discovered. It is a series of all-carbon molecules with a closed cage structure composed of a five-membered ring and a six-membered ring. Due to the perfect symmetrical structure of fullerenes, the special stability in the nano-scale range, and the strange electronic structure, it has become an irreplaceable material with great application poten...

According to different aggregation states, substances can be divided into steady state, unsteady state and metastable state. Generally, bulk materials are stable; particles with a particle size of about 2nm are unstable, and their structure is constantly changing when observed under a high-power electron microscope; and powders with a particle size of about micrometers are in a metastable state. T...
