An oxide of barium (or barytum); a heavy earth with a specific gravity above 4.

kalies; having the properties of an alkali. Alkaline earths, certain substances, as lime, baryta, strontia, and magnesia, possessing some of the qualities of alkalies. -- Alkaline metals, potassium, sodium, cæsium, lithium, rubidium. -- Alkaline reaction, a reaction indicating alkalinity, as by the action on limits,…

Baryta.

Symbol, Ba. Its oxide called baryta. [Rarely written barytum.]

Of or pertaining to baryta.

ng in white monoclinic crystals with pearly luster. It is a hydrous silicate of aluminia, baryta, and strontia.

A carbonate of baryta and lime, intermediate between witherite and strontianite; -- called also alstonite.

A similar oxide, having a slight alkaline reaction, as lime, magnesia, strontia, baryta.

h white zeolitic mineral, in tetragonal crystals. It is a hydrous silicate of alumina and baryta.

lline form, and all silicates of alumina with either potash, soda, lime, or, in one case, baryta. They occur in crystals and crystalline masses, vitreous in luster, and breaking rather easily in two directions at right angles to each other, or nearly so. The colors are usually white or nearly white, flesh-red, bluish,…

A hydrous silicate of alumina and baryta, occurring usually in white cruciform crystals; cross-stone.

poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydr…

An earth of a white color resembling lime in appearance, and baryta in many of its properties. It is an oxide of the metal strontium.

different oxides and water, with some oxide of iron, and often silica, alumina, lime, or baryta; black ocher. There are several varieties.

of a family of minerals, hydrous silicates of alumina, with lime, soda, potash, or rarely baryta. Here are included natrolite, stilbite, analcime, chabazite, thomsonite, heulandite, and others. These species occur of secondary origin in the cavities of amygdaloid, basalt, and lava, also, less frequently, in granite and…
