Spatial arrangement of fibrils in concentrated aqueous sols of fibrillar pseudoboehmite
(Elsevier B.V., 2002-09-01)
The particle size, aggregation state and spatial arrangements of the particles in concentrated sols of boehmite and of fibrillar pseudoboehmite are important parameters for determining the final properties of powders of ...
Hydrothermal synthesis of well-crystallised boehmite crystals of various shapes
(ABM, ABC, ABPolSão Carlos, 2009)
Aluminium monohydroxide, also known as aluminium oxyhydroxide (boehmite - AlO[OH]), is water insoluble but crystallises into microcrystals of various shapes. When, by X-ray diffraction, the microcrystals present a basal ...
Preparação de sóis aquosos de pseudoboemita com fibrilas de comprimentos diferentes
(Associação Brasileira de Cerâmica, 2009)
O mineral boemita, de composição (AlO)OH, na forma sintética pode ter estruturas cristalinas denominadas "boemita bem-cristalizada", "pseudoboemita" e "pseudoboemita fibrilar", caracterizáveis por difração de raios X e por ...
Specific surface area and structures of aluminas from fibrillar pseudoboehmite
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2008)
By heating powders of the aluminum monohydroxide fibrillar pseudoboehmite from 200 degrees C to 1400 degrees C several high surface area aluminas are prepared and characterized by X-ray diffraction and electron optical ...
