General description

Rutile titanium(IV) oxide, also called titanium dioxide, is a fine powder with a particle size less than 100 nm. This titanium adopts the rutile crystal structure and is a white, opaque, crystalline solid with a high refractive index. It is widely used as a pigment in paints, plastics, paper, and cosmetics. Rutile titanium dioxide nanopowder has a high surface area, making it more reactive and effective in a range of applications. It is resistant to heat and chemical attack, making it suitable for use in high-temperature and corrosive environments.

Application

  • A study on titanium dioxide nanoparticles synthesized from titanium isopropoxide under SILAR-induced gel method: Transition from anatase to rutile structure: This research explores the synthesis and phase transition of titanium dioxide nanoparticles from anatase to rutile structure using the SILAR-induced gel method (AC Nkele et al., 2020).
  • Synthesis of rutile TiO2 nanostructures by single step hydrothermal route and its characterization: This article describes the synthesis of rutile TiO2 nanostructures using a single-step hydrothermal method and their characterization (SB Wategaonkar et al., 2020).
  • Monolayer Intermixed Oxide Surfaces: Fe, Ni, Cr, and V Oxides on Rutile TiO2(011): The study investigates the formation of mixed oxide layers on rutile TiO2(011) and their structural properties (S Halpegamage et al., 2016).
  • Mechanism, thermodynamics and kinetics of rutile leaching process by sulfuric acid reactions: This research examines the dissolution of rutile in sulfuric acid, focusing on the thermodynamics and kinetics of the process (AV Dubenko et al., 2020).
  • Kinetics of anatase transition to rutile TiO2 from titanium dioxide precursor powders synthesized by a sol-gel process: This paper studies the phase transition kinetics of anatase to rutile TiO2 from sol-gel synthesized precursor powders (CL Wang et al., 2016).
