摘要： The present invention provides a method and apparatus for the controlled synthesis of nanoparticles using a high temperature process. The reactor chamber includes a high temperature gas heated by means such as a plasma torch, and a reaction chamber. The homogenizer includes a region between the reactant inlets and the plasma (the spacer zone) to ensure that feeds from the reactant inlets are downstream of the recirculation zone induced by the high temperature gas. It also includes a region downstream of the reactant inlets that provides a nearly 1 dimensional (varying only in the axial direction) flow and concentration profile in the reaction zone to produce nanoparticles with narrow size distribution.

摘要： Provided is a method for preparing rutile from acid-soluble titanium slag, including: grinding acid-soluble titanium slag; adding a sodium carbonate modifier, and performing microwave irradiation treatment in a microwave device; adding an ammonium bifluoride additive; and performing acid purification and calcination to obtain rutile. By means of a microwave heating mode, the equipment investment needed by the method is low, and the energy consumption is low. The purity of artificial rutile is more than 91%, byproducts are fewer, and the environmental pollution is low.

摘要： A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a D.C. arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory lining of the furnace and the molten bath and the process includes means to control the thickness of the frozen lining as well as the whole smelting process.
