The purpose of this study is to provide a comprehensive analysis of the global nanopowder market. Materials and methods. The study used such research methods as system-logical method, method of statistical generalization, comparative and factor analysis. Research results. It is known that nanopowders are obtained by chemical, physical, physico-chemical and mechanical methods. One of the major problems in the production of nanopowders is the tendency of nanoparticles to form aggregates and agglomerates that complicate the production of compact materials. To overcome the forces of agglomeration, a mechanical force or an increase in the sintering temperature must be applied. According to estimates from the consulting company Lux Research, in 2012, the nanotechnology market was $ 190.3 billion. Its annual growth is 15-17%. The world market leaders are the United States ($ 59 billion), Europe ($ 47 billion) and the Asia Pacific region ($ 9.4 billion). The US is the leader in both the commercial market and the number of publications (about 25,000 in 2015) and patents in nanotechnology (45% of patents). Following the results of 2015, more than $1.4 trillion worth of nanotechnology products were manufactured. In the structure of production of nanoproducts the chemical industry, scientific researches (intermediary products, as a rule, not serial) and electronics are leading. Global investments in nanotechnology in 2015 totaled $ 18.1 billion. This indicator increased by 18% compared to 2013. Corporate investments ($ 8.6 billion) became the main source of financing (public - only $ 8.3 billion). The leaders in terms of public investment are the US and the EU. Experts estimate that, by 2020, investment leadership may shift to Japan. Today, the leader in the nanomaterials market is the United States with a projected revenue level of 2018 of $ 1.46 billion. The main products on the world market for nanopowders are metal oxide powders. In the product group of metal oxides 4/5 the production volume accounts for the three most common types of raw materials: silica (SiO2), titanium dioxide (TiO2) and alumina (Al2O3). At the same time, silica occupies more than half of all production, alumina - 18% and titanium dioxide - 10%. The most available oxides are oxides of iron, zinc, cerium, zirconium, cuprum, magnesium, yttrium. The most complex oxides and mixtures are: tin oxide, barium titanate, cobalt carbide, silicon nitride and indium tin oxide. An analysis of the patents presented for nanopowder research has shown that the most promising area of scientific development is aluminum and precious metal nanopowders. Conclusions. Analysis of the world nanopowder market makes it possible to identify the following indicators that characterize its development: the common problem in the nanomaterials market is high cost of production, low volume of production and accessibility for the end consumer; the most developed nanopowder markets: USA, Europe and Asia-Pacific; projected growth rates during 2015-2020 The three largest components of the nanomaterials market: energy, production of catalysts, structural materials - 60%, 13% and 30% respectively; production of metal oxide products prevails in the world market of nanopowders; the most common types of raw materials: silica) - more than half of all production, titanium dioxide - 10% and alumina - 18%.
