Preparation of titanium carbide powder from ilmenite concentrate

EFFECT OF MECHANICAL ACTIVATION ON CARBOTHERMIC SYNTHESIS OF TITANIUM CARBIDE FROM ILMENITE CONCENTRATE

The synthesis of advanced materials from low cost minerals concentrates is a new field of study that has great potential applications. In this paper, the effect of milling time on the temperature of initiation and amount of carbothermic reduction of ilmenite has been investigated. The stoichiometric molar ratio (1:4) of ilmenite to graphite was mixed and mechanically activatedfor 30-70 hours at...

Production of Nanosized Synthetic Rutile from Ilmenite Concentrate by Sonochemical HCl and H2SO4 Leaching

Titanium dioxide is widely used in the manufacturing of paints, varnishes, lacquer, paper, paperboard, printing inks, rubber, floor covering, and ceramics and so on. White titanium dioxide pigment has been produced by two main processes. The sulfate and the chloride processes. Each of these two routes requires different feedstocks. However, economic and environmental pressures are shifting ...

Solubilization of cobalt from tungsten carbide–cobalt powder

Several reviews of the toxicology of cobalt, including toxicokinetic aspects, are available (IARC, 1991; Midtgård & Binderup, 1994; Lauwerys & Lison, 1994; Lison, 1996; Barceloux, 1999). This section will focus on the toxicokinetic data published since the previous IARC evaluation (1991) and potentially relevant for cancer. Particular emphasis will be put on studies that examined the fate of in...
