Calcium nitrate salt" 5Ca(NO).NHNO·10HO. This is called calcium ammonium nitrate. Formulations lacking ammonia are also known: Ca(NO)·4HO (11.9-0-0 + 16.9 Ca) and the water-free 17-0-0 + 23.6 Ca. A liquid formulation (9-0-0 + 11 Ca) is also offered. An anhydrous, air-stable derivative is the urea complex Ca(NO)·4[OC(NH)], which has been sold as Cal-Urea. Calcium nitrate is also used to control certain plant diseases. For example, dilute calcium nitrate (and calcium chloride) sprays are used to control bitter pit and cork spot in apple trees. Calcium nitrate is used in waste water pre-conditioning for odour emission prevention. The waste water pre-conditioning is based
Calcium stearate food additive it is known by the generic E number E470. Calcium stearate is a waxy material with low solubility in water, unlike traditional sodium and potassium soaps. It is also easy and cheap to produce, and exhibits low toxicity. These attributes are the basis of many of its applications. Related applications exist for the magnesium stearate. Calcium stearate Calcium stearate is a carboxylate of calcium, classified as a calcium soap. It is a component of some lubricants, surfactants, as well as many foodstuffs. It is a white waxy powder. Calcium stearate is produced by heating stearic acid and calcium
