Originally a hypothetical mineral named by Henry Stevens Washington [1867-1934] in 1903. First used to name natural material in 1935 by Norman L. Bowen. Clinoferrosilite, Hemleyite, Hiroseite, Pyroxferroite, Roedderite.
Ferrosilite (FeSiO 3 ): Synthesis at High Pressures and Temperatures …
The FeSiO 3 (ferrosilite) end member of the pyroxene series is not known as a pure mineral in nature and cannot be synthesized at atmospheric pressure. It is readily synthesized, however, at pressures from 18 to 45 kb and temperatures from 1150° to 1400°C.
In medium- to high-grade metamorphosed iron formations. Magnetite, hematite, ferroan diopside, quartz, almandine. Distribution: From Bauchi, Nigeria. At Tiris, Mauritania. From Oribi Gorge, Marble Delta, Natal, South Africa.
Enstatite - Wikipedia
Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO 3) – ferrosilite (FeSiO 3). The magnesium rich members of the solid solution series are common rock-forming minerals found in igneous and metamorphic rocks. The intermediate composition, (Mg,Fe)SiO.

Green prismatic and sometimes platy ferrosilite crystals, with blue rounded roedderite crystals in a cavity that formed around what appears to be a partially dissolved microperthitic white feldspar …
Ferrosilicon - Wikipedia
Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose. [5] .

Results showed that Fe 3 § substitutes for Si within the tetrahedral sites and that the Fe distribution is fully disordered. The octahedral sites are preferentially occupied by Mg. The presence of Fe 3+ within the tetrahedral sheet produces increased cell edge lengths.
