Product Name
Name: Small particle size nano titanium dioxide powder
Product Overview
Anatase nano titanium dioxide is an important form of nanoscale titanium dioxide, which has many unique physical and chemical properties and is widely used in multiple fields. Titanium dioxide is an acidic amphoteric oxide with extremely stable chemical properties. It hardly reacts with other elements and compounds at room temperature and is insoluble in water, fatty acids, other organic acids, and weak inorganic acids. It is slightly soluble in alkali and hot nitric acid. But under long-term boiling conditions, it can completely dissolve in concentrated sulfuric acid and hydrofluoric acid, producing titanium sulfate or titanium oxysulfate and fluorotitanate, respectively. It has photochemical activity, suspended in certain organic media, and can undergo continuous redox reactions under the action of light. Titanium dioxide has three crystal forms in nature, namely rutile type, rutile type, and perovskite type. Among them, the rutile type is the most stable, while the rutile type is stable at room temperature, but will transform to the rutile type at high temperatures. The perovskite type belongs to the orthorhombic crystal system and is an unstable crystal form. It will transform into the pyrite type above 650 ¡ãCand has no practical value in industry.
