Calcium chloride Formula - Calcium chloride Uses

It has a density of 2.15 g/mL, melting point of 782 °C and a high boiling point over 1600 °C. Chemical properties: CaCl 2 is highly water soluble, hygroscopic (absorbs moisture from air) and deliquescent (absorbs enough water to turn into liquid). Calcium chloride dissolves in water in a very exothermic manner (releasing a large amount of heat).

Calcium Metal - an overview | ScienceDirect Topics

Using the same set-up it is possible to make rare earth metal from oxides. The rare earth oxide is reacted with Ca to form rare earth metal and calcium oxide. Since CaO is a high melting point oxide, lower temperature is achieved by addition of a suitable halide salt mixture which can lower the melting point of the products of the reaction.

Melting Point of Metals & Alloys | Toolbox | AMERICAN

The melting point of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance''s melting point depends on pressure and is usually specified at standard pressure in reference materials.

why does calcium fluoride have a higher melting point than

Sep 06, 2007· Best Answer: Calcium fluoride (CaF2) is an insoluble ionic compound of calcium and fluorine. Strong charge-charge electric atraction exists between every pair of closely loed Ca and F ions, hence the melting point must be very high. On the other hand, F2 is a non-polar molecule.

Calcium - Melting Point - Boiling Point - Nuclear Power

Note that, these points are associated with the standard atmospheric pressure.. Boiling Point – Saturation. In thermodynamics, the term saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure. The temperature at which vaporization (boiling) starts to occur for a given pressure is called the saturation temperature or boiling

Melting and boiling points Group 1 and Group 2 metals

Calcium metal from Wikipedia As the graphs show the Group 2 metals have much higher melting points and boiling points than the Group 1 elements. The trend in the boiling points is an indiion of stronger metallic bonding in the Group 2 metals than for Group 1.

explain why the melting point of magnesium is higher than

Sep 07, 2007· Magnesium has a higher molar mass than sodium. Molar mass can contribute to the strength of the intermolecular forces of attraction. The relatively higher molar mass of magnesium makes its IMFA harder to break, requiring more energy, so you would have to place it at a higher …

Group 2- trend in melting points - The Science Forum

Feb 27, 2014· That means that starting from calcium, ionic character takes precedence and the general trend of metallic bond melting points takes place like the alkali metals. Because calcium''s ionic lattice happens to be higher in energy than magnesium''s covalent lattice, calcium has a higher melting point. It''s confusing looking at the melting points of
