The formula of a chemical mixture for increasing the hardness of steel produced at the enterprises of the Ministry of industry and construction of Turkmenistan was developed by employees of the laboratory "Chemical production technologies" Of the Institute of chemistry of the ants.

Silicon-iron alloy - ferrosilicon was obtained experimentally from local raw materials at the factory "Turkmendemironumleri" ("Turkmensteel").

- We have obtained a material that has the required physical and chemical properties at a low cost, - says senior researcher of the laboratory G. Amannazarov. - Turkmen ferrosilicon-41 can be successfully used in the foundry and metallurgical industry, replacing the expensive imported analog.

For the production of ferrosilicon, the laboratory staff of the Institute of chemistry used local raw materials: quartz sand from the "Myane" Deposit in the Kaka etrap, hot coke and graphite from the Turkmenbashi complex of oil refineries, iron shavings and scale from the metallurgical enterprise.

Now the laboratory staff is working on increasing the content of silicon in the additive, which will expand the limit of strength characteristics of steel, "Turkmenistan: Golden age" reports.
