Rutile is a mineral composed primarily of titanium dioxide (TiO₂), and is the most common natural form of TiO₂. Other rarer polymorphs of TiO₂ are known including anatase, akaogiite, and brookite. Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high dispersion. Owing to these properties, it is useful for the manufacture of certain optical elements, especially polarization optics, for longer visible and infrared wavelengths up to about 4.5 μm.

Static-conducting and anti-corrosive coating on inner wall of oil tank, and preparation method of static-conducting and anti-corrosive coating

InactiveCN104098989ALight colorEasy for visual inspectionAnti-corrosive paintsEpoxy resin coatingsPetrochemicalReactive diluent

The invention discloses a static-conducting and anti-corrosive coating and a preparation method thereof. The static-conducting and anti-corrosive coating comprises bisphenol A epoxy resin, a reactive diluent, rutile titanium dioxide, conductive mica powder, a coupling agent and a flexibilizer. The bisphenol A epoxy resin is ground; the reactive diluent, the flexibilizer, the coupling agent and a light-colored static-conducting material are added; and the coating free of an inertial and volatile solvent is prepared. The coating has the characteristics of high cohesion, good closure and stable static conductivity, is suitable for internal anti-corrosive and static-conducting protection of oil storage and transport equipment such as an oil storage tank, an oil transport pipeline and an oil transport tank in the petrochemical industry, and is also suitable for anti-corrosive and anti-static protection of a gas tank, a water gate and an underground pipeline.

Method of preparing artificial rutile with ferric salt solution leaching method

InactiveCN107043128ASpeed up the leaching reactionAvoid chalkingIron oxides/hydroxidesIron sulfatesHigh energyTitanium tetrachloride

The invention relates to a method of preparing artificial rutile with a ferric salt solution leaching method and belongs to the technical field of chemical metallurgy. The method of preparing high-grade artificial rutile by taking sand titanium concentrates as a raw material is simple in process and equipment, convenient to operate and low in production cost and overcomes the defects of higher energy consumption and difficulty in treating waste liquid. The method comprises the following steps: titanium concentrate strong reduction, ferric salt solution leaching, solid-liquid separation, solid substance washing and drying and filtrate purification. The method of preparing the artificial rutile with the ferric salt solution leaching method enables titanium oxides to form a more stable porous solid solution structure by controlling atmosphere and adopting high-temperature strong reduction, accelerates the leaching reaction speed of iron and prevents titanium-containing particles from pulverizing at the same time; and the obtained artificial rutile as a product is better in particle size distribution and proper in particle size and is an ideal raw material for producing titanium tetrachloride by fluidizing chlorination.
