Equilibrium pressures of hydrogen chloride and water vapour over solid or liquid barium chloride have been measured between 1173 K and 1473 K. All other gases were excluded from the system. The corresponding equilibria were represented by the following reactions: BaCl 2( s) + H 2 O( g) BaO...
1.SymbolBaA soft, silvery-white or yellowish-white alkaline-earth metal, used to deoxidize copper and to absorb trace gases in vacuum tubes, and used in various alloys. Atomic number 56; atomic weight 137.33; melting point 727°C; boiling point 1,897°C; specific gravity 3.62; valence 2....
The method comprises: (1) contacting waste lead paste with a barium-containing desulphurizer under desulphurization reaction conditions, and performing a solid-liquid separation on the mixture after contacting to obtain a filtrate and a filtration residue; and (2) performing a conversion reaction on...

Barium alloy, pyrophoric is mixture of barium and other metals or nonmetallic elements to improve the specific usefulness of barium. Barium alloys are a solid and can ignite spontaneously in contact with air. Barium is toxic and products given off in fire could be very toxic. ...
barium is a white liquid that is visible on x-rays. barium passes through the digestive system and does not cause a person any harm. as it passes through the body, barium coats the inside of the food pipe, stomach, or bowel, causing the outlines of the organs to appear on x-ray. ...

An x-ray luminescent phosphor composition consists essentially of a europium activated barium fluorochloride and an effective amount of brightness enhancement additive selected from lead, thallium and aluminum ions. The compositions are prepared by a solid state process in which a barium chloride and ba...
(a hydrocarbon liquid). q4 how do you make barium sulphate? the barium sulphate is prepared by sodium sulphate reacting to barium chloride. the precipitate forms the barium sulphate. q5 is barium sulphate an acid or base? baso4 is known as barium sulphate. this is salt. salt can be ...
Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral “barite” can vary between red, yellow, gray or green, depending on impurities. Its density is 4.50 g/cm3and its refractive index is 1.64. It melts around 1580°C...
