• The dehydration behaviors of two different hydrated zinc borate species, ... and ..., which are industrially important flame retardants, were studied by thermal gravimetric(TG) analysis and in situ diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy. Dehydration onset temperatures of ... and ... were 129 and 320...C, respectively, at a 10...C/min ramp rate. A very small amount of boric acid was volatilized in addition to water vapor when both samples were heated at 250...C. A significant amount of water vapor was adsorbed by ... from air at 25...C. However, ... adsorbed a very small amount of water under the same conditions. Both zinc borates did not have a tendency to cake during storage. (ProQuest: ... denotes formulae/symbols omitted.)
