PRODUCTION OF SILVER LOADED PHOTOCATALYTIC TIO2 POWDERS BY BALL MILLING
Aysin, Basak; PARK, JONGEE; Öztürk, Abdullah (2011-09-23)
The present study was undertaken to improve photocatalytic efficiency of TiO2 powder by silver doping and/or particle size reduction through mechanical ball milling. A planetary ball mill was employed to reduce the particle size of TiO2 powders to nanoscale and silver loading to TiO2 powders. Silver nitrate was used as silver source to obtain about 1% Ag load. Slurry taken from ball mill was separated by centrifugal separator into nano and micro sols. Separated nanosol was taken into the furnace to be dried...

Production of in situ aluminum-titanium diboride master alloy formed by slag-metal reaction
CHANGIZI, Ahmad; Kalkanlı, Ali; SEVINC, NACİ (Elsevier BV, 2011-01-12)
Al-TiB(2) master alloys have received much attention in recent years owing to their potential as efficient grain refiners for aluminum foundry alloys. In this study, the process of production of master alloys was investigated to develop a low cost method, namely, slag-metal reaction. This method can be used to fabricate Al-TiB2 master alloy in situ from the TiO(2)-H(3)BO(3)-Na(3)AlF(6) and Al system. Since the price of the raw materials is low and the technology is simple, the processing technique appears t...

Production of copper-based shape memory alloy using powder metallurgy methods
Ögel, Bilgehan; Dericioğlu, Arcan Fehmi ( Türk Toz Metalurjisi Derneği; 1999-12-01)
A Cu-based shape memory alloy is produced using PM methods. The Cu-16.5Zn-6.5Al alloy is prepared from elemental powders. The production route includes the various combination of sintering, hot pressing and hot rolling. Zinc loss due to evaporation could not be avoided in conventional compaction and sintering route. On the other hand, a homogenization treatment after hot pressing leads to formation of pores in the microstructure. Directly hot rolled specimens after a hot pressing operation showed shape memo...
