INTRODUCTION
In this article, we've compiled the physical properties of various mineral compounds, also sometimes referred to as inorganic compounds, listed in alphabetical order by element.
We had to eliminate astatine,francium andpromethium, which are highly unstable and whose physical properties are poorly understood. Similarly, for technetium, we have only given properties for the element and one oxide.
For each body, we have given the following characteristics: name, chemical composition and synonyms, molecular weight, density and/or specific gravity, melting temperature, boiling temperature, solubility in cold water, in hot water, in other solvents, crystal forms, properties and refractive indices (three values for biaxial anisotropic crystals, two values for uniaxial anisotropic crystals, one value for isotropic crystals).
Double and/or complex salts are classified with one or other of their constituent metals.
Density is usually given at 20°C, the reference body being water at 4°C. If this is not the case, the value is followed by the temperature (in °C) at which the body has this density, in superscript, and the temperature (in °C) of the water, in subscript. In the case of density, the unit is specified after the numerical value.
Melting and boiling temperatures are given in degrees Celsius. The temperature indicated is that observed under normal atmospheric pressure (i.e. 1 atm or 760 mm Hg). Otherwise, the temperature is followed by an exponent corresponding to the pressure in millimeters of mercury or atmospheres; for example, 180 20 = boiling temperature of 180°C at 20 mm Hg or 120 3atm = boiling temperature of 120°C at 3 atm.
If the letter appears next to a value, this means that the body decomposes at that temperature. If the letter stands alone, this means that the body decomposes...
