Silex maintains close relationships with other silicon producing manufacturers in China, allowing us to provide our clients in Europe, Japan and Malaysia with regular suppliers of silicon metal.

Silicon metal is produced by smelting quartz and coke in the electric furnace. The content of silicon is about 98%, and the remaining impurities are iron, aluminum and calcium. Silicon metal is mainly used as an additive in non – ferrous alloys. Silicon metal has semiconductor properties similar to germanium, lead and tin. It is insoluble in acid and soluble in alkali at room temperature.

 Silex specializes in import of high iron manganese and supplies regular cargoes of manganese ore to our clients in China. Through our trading relationship with manganese manufactures in South Africa, we are able to meet the increasing manganese demands.

In modern industry, manganese and its compounds are used in various fields of national economy. Among them, iron and steel industry is the most important field, with manganese content accounting for 90% ~ 95%, mainly used as deoxidizer and desulfurizer in the process of iron making and steelmaking, and used to make alloys. The remaining 10% ~ 5% manganese is used in other industrial fields, such as chemical industry (manufacture of various kinds of manganese salts), light industry (used in batteries, matches, printing paint, soap making, etc.), building materials industry (colorant and discolorant for glass and ceramics), national defense industry, electronics industry, environmental protection, agriculture and animal husbandry.,etc.
