Unprocessed phosphate rock has a concentration of 1.7–8.7% phosphorus by mass (4–20% phosphorus pentoxide). By comparison, the Earth's crust contains 0.1% phosphorus by mass, [84] and vegetation 0.03–0.2%. [85] Although quadrillions of tons of phosphorus exist in the Earth's crust, [86] these are currently not economically extractable.
Phosphor bronze propeller salvaged from 1940s American warship.. Phosphor bronze is a member of the family of copper alloys.It is composed of copper that is alloyed with 0.5–11% of tin and 0.01–0.35% phosphorus, and may contain other elements to confer specific properties (e.g. lead at 0.5–3.0% to form free-machining phosphor bronze).
Only the index phosphor stripe was used for tracking, and it was the only phosphor that was not covered by an aluminum layer. [327] It was shelved because of the precision required to produce it. [ 480 ] [ 481 ] It was revived by Sony in the 1980s as the Indextron but its adoption was limited, at least in part due to the development of LCD ...
The vertical warp yarns are held stationary in tension on a loom (frame) while the horizontal weft (also called the woof) is drawn through (inserted over and under) the warp thread. [1] In the terminology of weaving, each warp thread is called a warp end (synonymous terms are fill yarn and filling yarn ); a pick is a single weft thread that ...
