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 percentages of nickel, lead and iron. During the later part of first millennium BC the use of brass spread across a wide geographical area from Britain and Spain in the west to Iran, and India in the east. This seems to have been encouraged by exports and influence from the Middle East and eastern Mediterranean where deliberate production of brass from metallic copper and zinc ores had been introduced. The 4th century BC writer Theopompus, quoted by Strabo, describes how heating earth from Andeira in Turkey produced "droplets of false silver", probably metallic zinc, which could be used to turn
