High Purity Ti₃O₅ Slug for Optical Coatings - Leading China Suppliers & Factory Solutions
Application
Optical Coating
As a high refractive index material, it is used to deposit titanium dioxide (TiO₂) films to improve the light transmittance, reflectance and damage resistance of optical devices.
Anti-reflection film and beamsplitter: reduce the loss of lens reflection and improve imaging clarity (such as camera lenses, microscopes).
Used in laser systems and infrared sensors to optimize the optical response of specific wavelengths.
Glasses anti-glare film, cool light film (energy-saving lighting), automotive glass insulation film.
Functional Coating Material
In Ti-Si-C plasma spray coatings, Ti₃O₅ is used as a secondary phase (coexisting with TiC and Ti₅Si₃), which can improve coating hardness (up to 1980 HV) and high temperature oxidation resistance (5 times that of titanium alloys at 800°C).
Doped in alumina (Al₂O₃) bioceramics, artificial bone or dental implants are made by DLP 3D printing, taking into account mechanical strength (compressive strength increased to 7.07 MPa) and biocompatibility.
Nuclear & New Energy
Compounded with rare earth oxides (such as Dy₂O₃, Tb₄O₇) for nuclear reactor control rods, Tb₂TiO₅-Dy₂TiO₅ ceramics are made through high-energy ball milling-sintering process, with low coefficient of thermal expansion (optimized radiation stability).
Alloy Additives
As an additive to Ti-4Si alloy (accounting for 5wt%), it works with Zr/Y₂O₃ to improve the thermal corrosion resistance and wear resistance of the alloy, and is suitable for high-temperature aero engine components.

Frequently Asked Questions
What is the primary function of Ti₃O₅ in optical coatings?
Ti₃O₅ is a high refractive index material used to deposit titanium dioxide (TiO₂) films. It improves light transmittance, reflectance, and damage resistance in optical devices like camera lenses, microscopes, and laser systems.
How does Ti₃O₅ enhance the properties of wear-resistant coatings?
In Ti-Si-C plasma spray coatings, Ti₃O₅ acts as a secondary phase coexisting with TiC and Ti₅Si₃. This structure boosts coating hardness up to 1980 HV and increases high-temperature oxidation resistance by 5 times at 800°C compared to standard titanium alloys.
Why is Ti₃O₅ doped into bioceramics for medical implants?
When doped into alumina (Al₂O₃) bioceramics for 3D-printed artificial bones or dental implants, Ti₃O₅ significantly enhances mechanical strength—raising compressive strength up to 7.07 MPa—while maintaining excellent biocompatibility.
How does Ti₃O₅ contribute to nuclear reactor technology?
Ti₃O₅ is compounded with rare earth oxides such as Dy₂O₃ and Tb₄O₇ to form Tb₂TiO₅-Dy₂TiO₅ ceramics. Used in reactor control rods, these materials provide a low coefficient of thermal expansion, which optimizes radiation stability under extreme conditions.
What are the benefits of using Ti₃O₅ as an alloy additive?
When added to Ti-4Si alloys (around 5wt%) in combination with Zr/Y₂O₃, Ti₃O₅ strengthens the titanium-based alloy. It improves both thermal corrosion resistance and wear resistance, making it ideal for high-temperature aero engine components.
