Tungsten oxide (blue) (BTO) - An oxygen-deficient intermediate material. High-purity powder, ideal for batteries, sensors, coloring agents, photocatalytic materials, and thermal shielding materials!
■What is Tungsten Oxide (Blue) (BTO)■ Tungsten Oxide (Blue) (BTO) is a powdery compound that ranges from deep blue to blue-black and is an intermediate oxide containing oxygen vacancies. With high purity (over 99.95%) and excellent conductivity and light responsiveness, it is gaining attention as a multifunctional material, particularly in the fields of electronics and energy. ■Key Points of the Proposal■ Due to its unique electronic structure, BTO allows for applications that differ from conventional WO₃. - Battery Materials: Utilized in lithium-ion battery anodes, leveraging its conductivity. - Sensor Materials: Functions effectively as a gas sensor due to its high sensitivity resulting from oxygen vacancies. - Coloring and Pigment Applications: Exhibits a metallic blue luster, making it ideal as a coloring agent for glass and ceramics. - Precursor Applications: Also used as a reducing precursor for the production of tungsten powder. ⇒ Tungsten Oxide (Blue) combines multifunctionality with versatility as an intermediate material, making it suitable for a wide range of applications from research and development to mass production. It is also expected to be utilized as an advanced functional material in thermal shielding and electrochromic applications. Please feel free to contact us with any questions or requests for samples.
