Preparation and characterization of nanocrystalline titania powders by sonochemical synthesis
Nanocrystalline mesoporous titania powders were synthesized by hydrolyzing titanium isopropoxide in ethanol-water mixtures which were ultrasonically treated without using any templates or chemicals. Titanium isopropoxide-ethanol ...
Thermal behaviour of a zeolitic tuff
Natural zeolites undergo structural changes after heating which open their possible use in different fields, related to their chemical and physical properties, such as building stone, lightweight aggregate, ceramic foam, ...
Preparation and microstuructural development of nanocrystalline titania and alumina
(Trans Tech Publications, 2004)
The preparation of nanocrystalline titania and alumina was investigated by sol-gel methods using titanium isopropoxide, boehmite and aluminum isopropoxide. Various drying control chemical additives like oxalic acid, ...
