Ferrophosphorus is a ferroalloy, an alloy of iron and phosphorus. It contains high proportion of iron phosphides, Fe 2 P and Fe 3 P. Its CAS number is 8049-19-2. The usual grades contain either 18 or 25% of phosphorus. [1] It is a gray solid material with melting point between 1050-1100 °C. It may liberate phosphine in contact with water. Very ...
Iron tests are groups of clinical chemistry laboratory blood tests that are used to evaluate body iron stores or the iron level in blood serum. Other terms used for the same tests are iron panel , iron profile , iron indices , iron status or iron studies .
One such impurity—and the most important one—is iron oxide. Iron oxide impurities are reduced and form iron phosphides. The resulting second liquid product is called ferrophosphorus. Iron is considered an impurity and undesirable because it requires additional carbon and power for reduction. Thus, it locks up a certain percentage of the ...
A metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R 3 P (R = alkyl, aryl).
The TSI slant is a test tube that contains agar, a pH-sensitive dye , 1% lactose, 1% sucrose, 0.1% glucose, [2] and sodium thiosulfate and ferrous sulfate or ferrous ammonium sulfate. All of these ingredients are mixed together, heated to sterility, and allowed to solidify in the test tube at a slanted angle.

Before 1989, the only time the NFL played on Christmas was a pair of playoff games in 1971. The NFL adjusted its schedule when Christmas fell on a Sunday to avoid holding games on that day.
Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength. [4] Some of the colors that have been manufactured in addition to the common phosphors are green, red, blue, yellow, purple, orange, and white.
