Biography & Contributions

Ferdinand-Frederic-Henri Moissan was a French chemist born on September 28, 1852 – died on February 20, 1907. Moissan well noted for his isolation of fluorine gas and development of Moissan electric furnace. He devised a commercially profitable method of producing acetylene.

Moissan was the winner of Davy medal in the year of 1896, Elliott Cresson Medal in the year of 1989 and prestigious award Nobel Prize in the year of 1906.

He published his first scientific paper, about carbon dioxide and oxygen metabolism in plants. During the period of 1880s, Moissan focused on fluorine chemistry in specific the production of fluorine itself.

He discovered numerous fluorine compounds, such as SF6 in 1901. His research in the production of boron and artificial diamonds and the development of an electrically heated oven capable of reaching 3500°C using 2200 amperes at 80 volts followed by 1900.

He developed arc furnace which led to the production of borides and carbides of numerous elements. Moissan eventually succeeded in preparing fluorine in 1886 by the electrolysis of a solution of potassium hydrogen difluoride (KHF2) in liquid hydrogen fluoride (HF).

In 1893, Moissan began studying fragments of a meteorite found in Meteor Crater. In these crater Moissan found some fragment’s mineral made of silicon carbide. In 1905, this mineral was named moissanite.

Moissan electric furnace opened the field of high-temperature chemistry, enabling the reduction of metal oxides with carbon, and resulting in production of chromium, tungsten, titanium, and zirconium. He also prepared carbides, borides, and silicides.

Electric Arc Furnace

Electric Arc Furnace is a furnace that heats charged material by means of an electric arc. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C, while laboratory units can exceed 3,000 °C. Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc, and the current in the furnace terminals passes through the charged material. An electric arc furnace used for steelmaking consists of a refractory-lined vessel, usually water-cooled in larger sizes, covered with a retractable roof, and through which one or more graphite electrodes enter the furnace.
