Calcium sulfate (better known commercially as DrieriteT) is created by the controlled dehydration of gypsum. It is a general purpose desiccant geared mainly toward laboratory use. It is chemically stable, non-disintegrating, nontoxic, non-corrosive and does not release its adsorbed water easily when exposed to higher aient temperatures.
Calcium — Wikipédia
Le calcium est l''élément chimique de numéro atomique 20, de syole Ca. C''est un métal alcalino-terreux gris-blanc et assez dur. Il n''existe pas à l''état de corps pur dans la nature. C''est le cinquième élément le plus abondant de la croûte terrestre (plus de 3 %). Il est vital pour de noreuses espèces : formation des os, des dents

USES: This mediion is used to prevent or treat low blood calcium levels in people who do not get enough calcium from their diets. It may be used to treat conditions caused by low calcium levels such as bone loss ( osteoporosis ), weak bones (osteomalacia/ rickets ), decreased activity of the parathyroid gland ( hypoparathyroidism ), and a certain muscle disease (latent tetany).
Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
