Understanding Calcium Sulfonate Thickeners
2020/8/6· Calcium sulfonate greases are also used in motor-operated steam valves to control high-pressure steam. These steam valves are typically found in nuclear plants and thermal-generating stations. An article in NLGI Spokesman , July 2002 2 , supports that the calcite particles, inherent in calcium sulfonate greases, make them a good choice for high-temperature appliions.

Why is calcium a metal? Why does it seem to have so …
Elemental calcium is indeed a metal, although a reactive one that tends to oxidize in air because of reaction with oxygen. The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate , and other calcium salts.
Calcium metal was not available in large scale until the beginning of the 20th century. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same coination of these atoms.
