Frederick Mark BecketDied 1 Dec 1942 at age 67 (born 11 Jan 1875).Canadian metallurgist who held more than one hundred patents, covering a wide range of electric furnace and chemical products, notably ferro-alloys, calcium carbide, and special chromium steels. He developed a process of using silicon instead of carbon as a reducing agent in metal production, thus making low-carbon ferroalloys and certain steels practical. His processes for the production of low carbon ferro-alloys had world-wide application. |
