Lime sulfur - Wikipedia

About 2.2:1 is the ratio (by weight) for compounding sulfur and quicklime; this makes the highest proportion of calcium pentasulfide. If calcium hydroxide (builders or hydrated lime) is used, an increase by 1/3 or more (to 115 g/L or more) might be used with the 192 g/L of sulfur. If the quicklime is 85%, 90%, or 95% pure, use 101 g/L, 96 g/L

Calcium - Element information, properties and uses

Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation. Calcium phosphate (also known as hydroxyapatite) is the mineral component of bones and teeth and is a particularly good example of how organisms fabrie ''living'' composite materials.

which form calcium phosphonate precipitate; and calcium carbonate, which can be used as a protective film at high calcite saturations. The key to the success of hodic inhibitors is the formation of a protective film at the metal surface while at the same time preventing bulk precipitation of scale, usually with the use of polymers.

Chapter 7. The Minerals 1

The level of phosphorus in the diet, however, sets the rate at which calcium is retained in the body. An increasing level of dietary phosphorus will be accompanied by increasing: retention of both mineral elements in body tissues, thus maintaining the ratio of calcium and phosphorus within narrow limits.
