Chemistry of Tungsten Oxide Bronzes

open access: yesInternational Journal of Refractory Metals and Hard Materials, 1995
Abstract Ammonium paratungstate (APT) is the generally accepted starting material in tungsten manufacturing. The dopants, which are responsible for the non-sag properties, are given to some tungsten oxide bronze (TOB)-type compounds which are formed by thermal reductive decomposition of APT.
