Hemodialysis with fluoride free water (and normal to low potassium and slightly higher calcium concentrations) should be considered in all cases of serious burns and may need to be repeated. Hypocalcemia (low calcium level in the blood) may be corrected with 10% calcium gluconate (0.1 to 0.2 mL/kg IV up to 10 mL, repeated as necessary).

calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.
Calcium Element: (Properties, Uses, and Discovery) - …
Adding some calcium into aluminum metal makes an alloy that is stronger than aluminum alone and improves bearings strength. Hydrogen can be stored in calcium metal because it reacts with calcium to form calcium hydrides, and extracting hydrogen gas back from the calcium is very easy.

9/3/2018· We have the equation: #CaCl_2(aq)+Na_2CO_3(aq)->2NaCl(aq)+CaCO_3(s)downarrow# This produces a precipitate of calcium carbonate, and can be collected by filtrating the mixture afterwards. Note that this is a precipitation reaction, where two aqueous solutions are mixed together and form an insoluble precipitate, which can be then filtered out to be collected.

Fluorine - Production and use | Britannica
Fluorine - Fluorine - Production and use: Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO4) is formed, which is insoluble in HF. The hydrogen fluoride is obtained in a fairly anhydrous state by
