Like strontium, it closely resembles calcium both in the properties of the metal and in the compounds which it forms.
strontium obtained from carbonate of strontia by Sir Humphry Davy.
The product, however, may be assumed to be a mixture (not a chemical combination) of calcium salicylate and strontium salicylate.
Apparently Bremer in 1898 was the first to introduce fluorides of calcium, barium, and strontium.
Chloride of strontium goes into solution, chloride of barium remaining undissolved.
For example, strontium fluoride is used in the red flame-arc whose radiant energy is rich in red and yellow.
Celestine is much used for the preparation of strontium hydrate, which is employed in refining beetroot sugar in Germany.
Calcium colors the flame orange-red, distinguished from strontium, by appearing gray when seen through blue glass.
A salt of potassium produced under144 the same circumstances a violet, strontium, a crimson colour, &c.
strontium salts are precipitated by sulphuric acid and alkaline carbonates and sulphate.
light metallic element, 1808, coined in Modern Latin by English chemist Sir Humphry Davy (1778-1829) from Strontian, name of a parish in Argyllshire, Scotland, the site of lead mines where strontium was first found.
strontium stron·ti·um (strŏn'chē-əm, -tē-əm, -shəm)
A soft, easily oxidized metallic element that ignites spontaneously in air when finely divided. Atomic number 38; atomic weight 87.62; melting point 777°C; boiling point 1,382°C; specific gravity 2.54; valence 2.
A soft, silvery metallic element of the alkaline-earth group that occurs naturally only as a sulfate or carbonate. One of its isotopes is used in the radiometric dating of rocks. Because strontium salts burn with a red flame, they are used to make fireworks and signal flares. Atomic number 38; atomic weight 87.62; melting point 769°C; boiling point 1,384°C; specific gravity 2.54; valence 2. See Periodic Table.
