Ferrates of manganese, zinc, cobalt and nickel are important functional materials. Among them, Mn-Zn and Ni-Zn ferrite are the largest high frequency soft magnets in the world, which are commonly used as magnetic materials for high frequency transformers, inductors and recording heads. Ferrate is [...]
The molecular formula of APT crystallization is 5(NH4)2O·12WO3·nH2O(n=5, 7, 11), and its solubility in water is very small, which increases slightly with the rise of temperature. Ammonium secondary tungstate crystallization is the main intermediate product for the preparation of blue tungsten oxide, ammonium tungsten [...]
1, the introduction
Coating is widely used in our daily life, and plays a protective, decorative and special role in the painted parts. The coating is mainly composed of film-forming substances (resin), fillers, additives and solvents (or water). With the development of industry and the [...]
1. Nano nickel oxide used in catalyst:
Nano-nio (VK-N10,VK-N30,VK-N150, wan King supply) is a good catalytic oxidation catalyst, Ni2+ has a 3D orbital, has the preferred adsorption tendency of multi-electron oxygen, also has the activation effect on other reducing gases, and the O2 of reducing [...]
Research progress of preparation methods of strontium titanate at present, the main preparation methods of strontium titanate are sol thermal method.
Sol-sol-whether in metallic materials, or in organic and inorganic non-metallic materials, adding appropriate amount of strontium and its compounds can change some of its [...]
Bismuth oxide is an important functional powder material, widely used in inorganic synthesis, electronic ceramics, chemical reagents and other fields, mainly used in the manufacture of ceramic dielectric vessels, can also be used in the manufacture of piezoelectric ceramics, varistors and other electronic ceramic [...]
Nano aluminum nitride powder has high specific surface area, high hardness, high thermal conductivity, high insulation and other characteristics, belongs to diamond-like nitride, can be stable to 2200℃, high strength at room temperature, good compatibility with the matrix interface, can improve the thermal conductivity [...]
Germanium telluride (GeTe) is a ferroelectric Rashba semiconductor with many interesting properties. The crystals are made of nanodomains whose ferroelectric polarization can be changed by an applied electric field. This ferroelectric property can also be used to change the spin of electrons in each [...]
1.The proportion of filler
When the filling amount of the thermal filler is small, the thermal contact between the thermal filler can not form a real contact and interaction, which is almost meaningless for improving the thermal conductivity of the polymer material. Only in the [...]
