Aluminum oxide is an inorganic substance with the chemical formula Al2O3. It is a high-hardness substance with a melting factor of 2054°& deg; C and also a boiling point of 2980°& deg; C. It is an ionic crystal that can be ionized at high temperatures and is commonly used in the manufacture of refractory products.
Aluminum oxide is a white solid hardly soluble in water, odorless, tasteless, and also extremely difficult in nature. It is simple to take in dampness however does not deliquescence (after shedding, it does not take in dampness). Light weight aluminum oxide is a normal amphoteric oxide (corundum is alpha-shaped and belongs to the hexagonal densest packing, is an inert substance, a little soluble in acid as well as antacids, corrosion resistance), soluble in not natural acids and also alkaline remedies, virtually insoluble in water and also non-polar Organic solvent; relative thickness (d204) 4.0; melting factor 2050 ℃.
Application of Nano Aluminum oxide
Lithium battery separator finish material:
High-purity Nano-Aluminum oxide is used as a ceramic finishing to be put on the favorable and unfavorable electrode separators of lithium batteries, which contribute in warm resistance, high-temperature resistance, and insulation, which can avoid the power battery from being overheated as a result of heat. Melted as well as short-circuited.
Lithium battery cathode material additives:
High-purity Nano-Aluminum oxide doped with lithium cobalt oxide, lithium manganate, and so on can enhance thermal stability, improve cycle performance as well as overcharge resistance, hinder oxygen generation as well as LiPF6 decomposition, and also prevent straight call in between LiCo02 and also electrolyte. Lower the electrochemical specific capability loss, thereby boosting the electrochemical certain capacity of LiCoO2.
Stimulant carrier:
High-purity γ& gamma;-kind Nano-Light weight aluminum oxide is a porous material, with an interior area of approximately numerous square meters per gram, high activity, and strong adsorption capacity. It is a commonly made use of adsorbent, stimulant, and catalyst service provider in the petroleum refining and petrochemical industry; it is a deacidification representative for transformer oil and generator oil in the industry; it is likewise made use of for chromatographic analysis; it is a neutral solid desiccant in the research laboratory. Its drying ability is no less than that of phosphorus pentoxide. After use, it can be regenerated and also recycled after home heating at 175°& deg; C for 6-8h.
Anti-caking of powder layer: Nano light weight aluminum oxide is made use of in powder finishes, which can increase the thickness of powder layers and has an excellent anti-caking result. In summer, Nano-Aluminum oxide can effectively prevent powder finishing from agglomerating and has great storage residential properties for powder finishes made use of in high temperature level and high moisture atmospheres.
Wear-resistant hardener for coverings, rubber, and plastics:
Adding 5-20% of Nano-Aluminum oxide, the ready layer can considerably boost the wear resistance and scratch-resistance of the covering, which is 2 to 5 times greater than the wear resistance of typical coatings. After adding Nano-Aluminum oxide in the paint, a really fine, consistent, and also really hard network framework can be created on the surface of the paint to protect the polymer paint layer listed below from damages. The anti-scratch performance of the Nano paint is better than the original The paint has actually been increased by 3 times as well as is commonly used in automobile paints. Including Nano light weight aluminum oxide can significantly boost the hardness of the layer, and also adding regarding 20% can get to 6-7H. Does not influence the transparency of the finish.
Thermal conductivity of plastics, rubbers, adhesives, and also finishings:
Light weight aluminum oxide solitary crystal has a thermal conductivity of 30, Nano-scale Light weight aluminum oxide has high thermal conductivity as well as a big amount of round dental filling. In order to enhance the compatibility of the resin matrix as well as the filler, and improve the thermal conductivity of the matrix product without reducing its mechanical residential properties, surface treatment representatives such as combining agents are frequently used for surface therapy, and also the thermal conductivity is dramatically enhanced.
Ceramics:
Nano Light weight aluminum oxide has high purity, consistent bit dimension, and good dispersibility. Adding about 10% of VK-L30 to sintered porcelains can enhance the molding pressure as well as lower the number of pores, thereby boosting the thickness of the ceramic green body, boosting the thickness and mechanical residential or commercial properties of Light weight aluminum oxide ceramics after sintering, and also minimizing the sintering temperature level much more effectively.
Powder metallurgy:
Nano Aluminum oxide for metallurgy, with tiny fragment dimension, huge particular area, high activity, adding 1-3% Nano Light weight aluminum oxide to prevent densification of the matrix as well as enlargement of crystal grains, enhanced solidity, improved conductivity, and also mechanical properties, and increased melting factor As well as high-temperature resistance.
Polishing:
Aluminum oxide has uniform bits and also a high spherical form. It is a precision polishing powder and also a good material for metallographic sprucing up. It is additionally suitable for stainless steel mirror sprucing up, titanium polishing, cast iron polishing, aluminum mirror sprucing up, stone mirror polishing, paint Sprucing up, material polishing, PCB circuit card sprucing up, glass polishing, optical glass, phenomenon lens polishing, resin lens sprucing up, sapphire sprucing up, LED polishing, germanium sprucing up, zinc sprucing up, fast sprucing up, excellent brightness, no scratches.
