Thermal decomposition and rehydration of strontium oxalate: morphological evolution
(Elsevier B.V., 2001-09-01)
Undoped and Eu3+ doped monohydrate strontium oxalate samples were precipitated under ultrasound and conventional stirring and were heated at different temperatures. All samples were characterized by X-ray powder diffraction ...
Thermal decomposition and rehydration of strontium oxalate: morphological evolution

Monolithic diphasic gels of mullite by sol-gel process under ultrasound stimulation
(1998-12-01)
Diphasic gel in the mullite composition was prepared from a colloidal sol of boehmite mixed with a hydrolyzed tetraethoxisilane (TEOS) solution. The boehmite sol was obtained by peptization of a poorly crystallized or very ...
Automatic microstructural characterization and classification using artificial intelligence techniques on ultrasound signals
(2013-06-15)
Secondary phases such as Laves and carbides are formed during the final solidification stages of nickel based superalloy coatings deposited during the gas tungsten arc welding cold wire process. However, when aged at high ...
