Silica fumes are relatively unfamiliar for Chinese people. But if talking about its use, it is a cornucopia to be developed. Development and utilization of foreign micro-silica fume has a 40-year history. The comprehensive utilization of silica fumes only has10 year’s history. The main use of the silica fume is in the field of refractories and concrete. The refractory only confines to the amorphous part. In recent years, with the gradually promotion, micro-silica fume is applied in the project sheet, wear-resistant floor coatings and functional mortar areas .It has been used in large-scale irrigation, tunnels and bridges project. It has opened up a wide range of outlets for Chinese rich silica fume.

Unique performance of AMD, high activity of silica fumes, and laid its preeminent position in the materials industry. By chemical synthesis or physical crushing of SiO2-based materials to achieve the fineness of silicon powder, the cost is quite expensive, but extremely difficult to meet the requirements of high activity. Therefore no exaggeration to say that the silica fume China national materials Industry will bring a revolutionary change. The researchers are actively engaged in applied research of micro-silica fume, and have achieved initial results. More R & D institutions in China to carry out such research will facilitate the silica fume career to a new level.

Silica fume in 2004 production reached 120,000 tons, most of which are 90 below grade. With the gradual implementation of national environmental policies, silica fume production will greatly improve the integration of resources of the silica fume, promote the use of the more urgent. States in the silica fume comprehensive utilization work started late, and in the construction field and the field of ceramics and other building materials, have a very lag gap with foreign high-end technology. After joining the WTO, the gap between technology development and utilization of micro-silica fume is narrowing, the main reason is the foreign end-customer production base has been moved to China, local procurement of silica fume; or foreign sourcing base as silica fume. In recent years, exports of Chinese silica fume are gradually increased, despite the expensive shipping cost constraints. The behavior of European countries purchasing large quantities of silica fume shows that silica fume products have a comparative advantage.

Industrial silicon and ferrosilicon project launched in recent years, many environmental dust collection project is a temporary installation, quality of equipment and worrying, the silica fume low quality and instability in the market. It is difficult to find a suitable location, which requires aroused the attention of the person concerned. Nickel powder industry is many favorable conditions, should take full advantage of this favorable opportunity, and actively carry out the export work. Silica fume export to Japan, South Korea, the Middle East market advantage of the price, quality silica fume will have a bright future in the European market.

In the past, silica fume market is monopolized by foreign companies. Firstly, China should be positive to learn from abroad. After all, their history is longer and more experienced. Foreign companies enter the Chinese market with imported silica fume in past. Then its high profile and technical barriers form a monopoly. In recent years this situation has completely changed. Foreign companies purchases Chinese domestic silica fume products and paste the foreign brands. The phenomenon is relatively common.Source:http://www.mhcmp.com
