Pulsed Electric Current Sintering and Its Employment for Transparent Polycrystalline Al₂O₃
Get PDFPulsed electric current sintering(PECS) has become more and more important in material sciences as an advanced method for meterial fabrication. The remarkable features of PECS in comparison with almost other sintering techniques are the direct heating method and the assistance of pressure. Therefore, PECS has fast heating rate and this sintering technique can densify samples fast without a severe grain growth. The high density and fine microstructure of materials sintered by PECS help a lot in improving properties of materials, especially mechanical properties. Recently, transparent polycrystalline Al₂O₃ has attracted much attention among ceramic materials. PECS is a superior sintering method for fabrication of transparent polycrystalline Al₂O₃.This article briefly summarizes the features of PECS and its recent advances in fabrication of transparent polycrystalline Al₂O₃.application/pdfdepartmental bulletin pape

Synthesis of Fumed Titanium Dioxide with a High Content of Rutile Structure by Novel Natural Dropping Thermal Treatment
Get PDFA natural dropping thermal treatment is an effective method to calcine materials with very short heating time. It has been applied to the transformation of titanium dioxide from anatase to rutile stucture. In particular, the novel thermal treatment is an indispensable method for the fumed titanium dioxide (Fumed TiO₂) to give high rutile structure content inhibiting the sintering/grain growth. Meanwhile, the relationships between conversion ratio of the rutile structure content and the morphology of the agglomerate before the thermal treatment(Precursor)has been investigated.application/pdfdepartmental bulletin pape
