2. Calcium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Calcium_hydroxide

   Limewater is a saturated aqueous solution of calcium hydroxide. Calcium hydroxide is sparsely soluble at room temperature in water (1.5 g/L at 25 °C [23]). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4.

3. Self-heating food packaging - Wikipedia

   en.wikipedia.org/wiki/Self-heating_food_packaging

   Commercial heat sources for self-heating food packaging use an exothermic (heat releasing) reaction, for which there are several common formulations. These include: Quicklime aka calcium oxide, and water. Quicklime, inexpensive and readily available, is generally recognized by the FDA as safe. [2] The product of the reaction is calcium hydroxide.

5. Bone ash - Wikipedia

   en.wikipedia.org/wiki/Bone_ash

   Typical bone ash consists of about 55.82% calcium oxide, 42.39% phosphorus pentoxide, and 1.79% water. [1] The exact composition of these compounds varies depending upon the type of bones being used, but generally the formula for bone ash is Ca 5 (OH)(PO 4) 3. Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 ...

6. Lime (material) - Wikipedia

   en.wikipedia.org/wiki/Lime_(material)

   An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.

7. Calcium oxide - Wikipedia

   en.wikipedia.org/wiki/Calcium_oxide

   One litre of water combines with approximately 3.1 kilograms (6.8 lb) of quicklime to give calcium hydroxide plus 3.54 MJ of energy. This process can be used to provide a convenient portable source of heat, as for on-the-spot food warming in a self-heating can, cooking, and heating water without open flames. Several companies sell cooking kits ...

8. Amorphous calcium phosphate - Wikipedia

   en.wikipedia.org/wiki/Amorphous_calcium_phosphate

   Amorphous calcium phosphate (ACP) is a glassy solid that is formed from the chemical decomposition of a mixture of dissolved phosphate and calcium salts (e.g. (NH 4) 2 HPO 4 + Ca(NO 3) 2). The resulting amorphous mixture consists mostly of calcium and phosphate, but also contains varying amounts of water and hydrogen and hydroxide ions ...
