Barito Pacific
Barito Pacific is a Jakarta-based Indonesian conglomerate founded by Prajogo Pangestu in 1979 as a timber business, listed since 1993, now centered on petrochemicals, geothermal power, and infrastructure.
Baritone
Baritone: the middle male classical voice type between tenor and bass, range about G2–G4, classified by tessitura and passaggio; Fach subtypes include Kavalierbariton, Heldenbariton, and Spielbariton, with roles such as Rigoletto, Scarpia, and Don Giovanni.
Baritone guitar
Baritone guitar: a six-string guitar with a 27-30 inch scale length, tuned a fourth or fifth below standard (typically B-E-A-D-F#-B), between guitar and bass; pioneered by Danelectro in 1956, used in country, metal, surf, and film scoring.
Baritone horn
Baritone horn: B-flat tenor brass instrument of the British brass band, cylindrical bore, three valves, brighter tone than the euphonium; descended from Sax's baritone saxhorn.
Baritone saxophone
Baritone saxophone (bari sax): largest common saxophone, pitched in E flat, sounding an octave and major sixth below written pitch. Invented by Adolphe Sax, 1842; standard low-A-equipped bass voice of big bands, quartets, and wind ensembles.
Barium
Barium, element 56, is a soft, silvery-white alkaline earth metal that reacts rapidly with air and water and is used chiefly as barite in drilling fluids.
Barium borate
Barium borate most commonly refers to beta barium borate (β-BaB₂O₄, BBO), a nonlinear optical crystal used for laser frequency conversion, including fifth harmonics of Nd:YAG lasers.
Barium caprylate
Barium caprylate, also called barium octanoate or barium octoate, is the barium salt of octanoic acid, a metallic soap used as a polymer heat stabilizer, paint drier, and ceramic precursor.
Barium cerate
Barium cerate (BaCeO₃) is a perovskite oxide ceramic that conducts protons at high temperatures, first shown in 1981, but it degrades in CO₂ and water vapor.
Barium chloride
Barium chloride (BaCl2) is a white, water-soluble salt of barium and one of the most acutely toxic soluble barium compounds, used mainly for purifying brine in caustic chlorine plants.
Barium enema
A barium enema is a radiographic exam in which barium sulfate instilled through the rectum coats the colon for X-ray imaging, used to detect polyps, cancer, and inflammatory disease.
Barium ferrite
Barium ferrite, also called barium hexaferrite, is a ferrimagnetic ceramic with formula BaFe12O19 and a hexagonal magnetoplumbite structure, widely used in permanent magnets, magnetic recording media, and microwave devices.
Barium fluoride
Barium fluoride (BaF₂) is an inorganic compound of barium and fluorine that crystallizes in the cubic fluorite structure and occurs naturally as the mineral frankdicksonite.
Barium fluosilicate
Barium fluosilicate (barium hexafluorosilicate, BaSiF6, CAS 17125-80-3) is a sparingly soluble white barium salt once widely used as an inorganic fluoride insecticide against beetles, now not approved in the EU.
Barium hydroxide
Barium hydroxide, also known as barium hydrate, is a white, strongly basic, water-soluble solid sold chiefly as its octahydrate and used in barium soaps and greases.
Barium nitrate
Barium nitrate (Ba(NO3)2, CAS 10022-31-8), also called barium dinitrate, is a white crystalline soluble barium salt and strong oxidizer used for green pyrotechnic fire, signal lights, barium oxide, and detonators; toxic via hypokalemia.
Barium oxide
Barium oxide (BaO), also called baryta, is a highly alkaline white powder that reacts violently with water and is used as a drying agent and cathode coating.
Barium peroxide
Barium peroxide (BaO2) is an inorganic peroxide of barium, a grayish-white powder and strong oxidizing agent that was the working chemical of the Brin process for industrial oxygen.
Barium polysulphide
Barium polysulphide (polybarit, bologna stone), BaS-based inorganic fungicide and rodenticide, discovered circa 1570; not approved in the EU under Regulation 1107/2009; obsolete, moderately toxic irritant.
Barium stannate
Barium stannate (BaSnO₃, often abbreviated BSO) is a wide-bandgap transparent semiconducting oxide with a cubic perovskite structure, notable for its high electron mobility when doped.
Barium star
A barium star, or Ba II star, is a chemically peculiar red giant with an atmosphere overabundant in barium and other heavy elements despite being too faint to make them.
Barium strontium cobalt ferrite
Ba0.5Sr0.5Co0.8Fe0.2O3, or BSCF, is a mixed-conducting perovskite oxide, benchmark electrocatalyst for the oxygen evolution reaction in alkaline media, and cathode material for solid oxide fuel cells.
Barium strontium titanate
Barium strontium titanate (BST) is a ferroelectric perovskite solid solution of barium titanate and strontium titanate whose dielectric constant is electrically tunable, making it valuable for microwave phase shifters, filters, and varactors.
Barium sulfate
Barium sulfate (BaSO4), the mineral barite, is a white insoluble salt used as a weighting agent in oil-well drilling muds and as a contrast material for x-ray imaging.
Barium titanate
Barium titanate (BaTiO₃) is a perovskite ceramic of barium, titanium, and oxygen, first ferroelectric oxide without hydrogen bonding and the main dielectric in multilayer ceramic capacitors.
