What is Alumina Nanoparticle used for
Lithium battery diaphragm finishing material:
High purity nano alumina is put on the favorable and negative diaphragm of lithium battery as a ceramic coating, which plays the duty of heat resistance, heat resistance and insulation, so as to prevent the power battery from short circuit because of high temperature and diaphragm melting.
Additives for cathode materials of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and also lithium manganate can improve thermal stability, cycle performance and overcharge resistance, inhibit the development of oxygen and the disintegration of LiPF6, prevent direct get in touch with between LiCo02 and also electrolyte, minimize the loss of electrochemical certain capacity, and enhance the electrochemical specific capacity of LiCoO2.
High purity γ& gamma;-kind nano-alumina is a porous material with an inner surface of numerous square meters per gram, high activity as well as solid adsorption capacity. It is a commonly used adsorbent, stimulant and also driver provider in petroleum refining as well as petrochemical industry; it is a deacidizing agent for transformer oil and generator oil in industry, and it is likewise used for chromatographic analysis; it is a neutral as well as solid desiccant busy, its drying capability is no less than that of phosphorus pentoxide, as well as it can be restored as well as recycled after heating below 175 ℃ for 6-8 hours.
Powder covering anti-caking:
In summer season, nano-alumina can effectively avoid powder layer caking. Nanometer aluminum trioxide utilized in powder finishings can improve the fluffiness of powder coverings and have great anti-caking impact. It has great storability for powder finishings utilized in heat as well as high humidity atmosphere.
Coating, rubber, plastic wear-resistant and also hardening agent:
Adding 5-20% nano-alumina, the finish can substantially enhance the wear resistance and scratch resistance of the finishing, which is 2-5 times higher than that of the conventional covering. After nano-alumina is contributed to the paint, an extremely fine, consistent and difficult network structure can be based on the paint surface area, which protects the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times higher than that of the original paint. it is extensively made use of in automobile paint and more. The enhancement of nano-aluminum trioxide can dramatically enhance the firmness of the coating, and also about 20% can reach 6-7H. The transparency of the coating is not influenced.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large spherical dental filling. In order to improve the compatibility of material matrix and fillers, boost the thermal conductivity of matrix products as well as not lower its mechanical residential properties, surface area treatment representatives such as combining agents are commonly made use of to enhance the thermal conductivity.
Nano alumina has high purity, consistent particle size and excellent dispersion. When around 10% alumina is contributed to the sintered porcelains, the forming pressure rises, which can lower the variety of pores, thus raise the density of the ceramic space, boost the thickness and mechanical properties of the sintered alumina porcelains, as well as decrease the sintering temperature level more effectively.
Nano alumina for metallurgy has small bit dimension, huge particular area and also high activity, adding 1-3% nano-alumina to avoid matrix densification as well as grain dimension, boost hardness, boost electrical conductivity as well as mechanical properties, as well as enhance melting point and high temperature resistance.
Alumina particles are consistent, have high sphericity, and are precision brightening powder, is a great material for metallographic sprucing up, yet additionally suitable for stainless steel mirror sprucing up, titanium sprucing up, cast iron sprucing up, light weight aluminum mirror sprucing up, rock mirror sprucing up, paint sprucing up, resin polishing, PCB circuit card sprucing up, glass sprucing up, optical glass, glasses lens sprucing up, material lens polishing, sapphire sprucing up, LED sprucing up, germanium polishing. Zinc sprucing up, quick polishing, good illumination, no scrapes.
