China's first tonnage fullerene production line put into operation

On July 12, the first domestic tonnage fullerene production line (Phase I) built by Inner Mongolia Carbon Valley Technology Co., Ltd. Which was recently put into operation in Hohhot, and the current production load has been Reached 80%. In the future, according to market needs, the company will also design an annual production capacity of 3 to 5 tons.

Fullerenes are the stars of the carbon material family, including C60, C70, C84, C90, C94, PCBM, etc. "The most common fullerene is C60, which is composed of 60 carbon atoms connected by 20 six-membered rings and 12 five-membered rings. It is an all-carbon molecule with an ultra-stable structure and resembling a football-like hollow symmetry. Also known as football olefins."   the stable structure and unique physicochemical properties of fullerenes make them available in solar cells, magnetic resonance contrast agents, and bioengineering genes. Carriers, laser goggles, and hepatitis C treatment, anti-influenza virus, anti-tumor and other fields are useful.

At present, the global market for fullerenes is about several billion US dollars. In the world, only a few countries such as the United States, Russia, and Japan have achieved mass production of fullerenes. The fullerene production line in the United States, Russia and other countries is in the kilogram class and is expensive. Japan's Mitsubishi's fullerene production first reached the tonnage, but mainly used for military industry, not for sale. China has included fullerenes in the "12th Five-Year" Key Product Catalogue of the New Materials Industry, and incorporated key nanocarbon materials and device key projects in the 13th Five-Year Plan.

Fullerene has a variety of structures, and the difficulty of synthesis varies, and the price changes are also large. The price of foreign related products ranges from several hundred yuan to several tens of thousands per 10,000, and sales are strictly controlled. Only through independent research and development and continuous innovation in production, purification and separation process technology can we no longer rely on imports to provide high-performance fullerene products for domestic downstream users.

According to reports, the company has overcome the key technology of fullerene purification, greatly improved separation efficiency and product quality, achieving high purity separation (99.9%) and high yield, complete independent intellectual property rights in preparation and separation technology, main production equipment All of them are independent research and development, breaking the monopoly of the US and Japan in the fullerene industry.

Inner Mongolia Carbon Valley Technology Co., Ltd have 7 invention patents and 7 utility model patents. In recent years, they have successively introduced civilian products such as fullerene lubricants, fullerene bacteriostatic agents and fullerene cosmetics, and experts in the field of materials at home and abroad. Collaborate to pioneerly add fullerenes to aluminum and copper metal materials. The lightweight high-strength fullerene laminated aluminum material prepared by the method has the ultimate bending strength equivalent to 45 steel, but the density is only one third of the steel, and is widely used in the weight reduction of airplanes, trains, automobiles, etc.; High-performance fullerene copper-based composite material with a friction coefficient of only one-third of pure copper, which can improve performance in high-speed rail grids, mechanical bushings, oil-impregnated bearings, copper-based balance blocks, etc.; developed fullerene vacuum coating Technology, can be used in bearings, microelectronic chips, solar cells and other fields.
