During the past 10 years particle engineering in the pharmaceutical industry has become a topic of increasing importance. Engineers and pharmacists need to understand and control a range of key unit manufacturing operations such as milling, granulation, crystallisation, powder mixing and dry powder inhaled drugs which can be very challenging. It has now become very clear that in many of these p...

Issues concerning powder consolidation methods compatible with the colloidal approach and issues associated with other powder processing steps, viz., den-sification and microstructural control, are presented with regard to research directions leading to more reliable ceramics. 1. Introduction With their multiplicity of elemental combinations and crystal structures, ceramics exhibit unique prope...

The synthesis of efficient ZnTe powder phosphors is very difficult due to its high moisture sensitivity and chemical instability during processing. In this study, an efficient ZnTe:O powder phosphor for x-ray imaging application was successfully synthesized by vacuum firing ZnTe powder prepared from ZnTe bulk crystals ball-milled in an O2 atmosphere. The phosphors were characterized by x-ray di...
