Barium orthotitanate is heating pellets of Ba(OH) and TiO. Additionally, there are polymer precursor, sol-gel and reverse micellar routes to BaTiO synthesis. BaTiO has also been successfully grown as a thin film with chemical vapor deposition. Barium orthotitanate can remove up to 99.9% of from a high-temperature gas stream by the reaction: Barium orthotitanate Barium orthotitanate is the inorganic compound with the chemical formula BaTiO. It is a colourless solid that is of interest because of its relationship to barium titanate, a useful electroceramic. The solid has two known phases: a low-temperature (β) phase with "P"2/"n" symmetry and a high-temperature (α′) phase
Brass instrument Traditionally the instruments are normally made of brass, polished and then lacquered to prevent corrosion. Some higher quality and higher cost instruments use gold or silver plating to prevent corrosion. Alternatives to brass include other alloys containing significant amounts of copper or silver. These alloys are biostatic due to the oligodynamic effect, and thus suppress growth of molds, fungi or bacteria. Brass instruments constructed from stainless steel or aluminium have good sound quality but are rapidly colonized by microorganisms and become unpleasant to play. Most higher quality instruments are designed to prevent or reduce galvanic corrosion between any steel in
