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
Sterling silver items in the “New World” ranging from simple buckles to ornate Rococo coffee pots. Although silversmiths of this era were typically familiar with all precious metals, they primarily worked in sterling silver. The colonies lacked an assay office during this time (the first would be established in 1814), so American silversmiths adhered to the standard set by the London Goldsmiths Company: sterling silver consisted of 91.5 - 92.5% by weight silver and 8.5–7.5 wt% copper. Stamping each of their pieces with their personal maker's mark, colonial silversmiths relied upon their own status to guarantee the quality and composition of their
