High Purity Ti₃O₅ Slug for Vacuum Coating - Top China Suppliers and Factory Quality
Application
Optical Coating
Functional positioning:
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.
Typical devices:
• Anti-reflection film and beamsplitter: reduce the loss of lens reflection and improve imaging clarity (such as camera lenses, microscopes);
• Filters and high reflection films: used in laser systems and infrared sensors to optimize the optical response of specific wavelengths;
• Special coatings: glasses anti-glare film, cool light film (energy-saving lighting), automotive glass insulation film.
• Filters and high reflection films: used in laser systems and infrared sensors to optimize the optical response of specific wavelengths;
• Special coatings: glasses anti-glare film, cool light film (energy-saving lighting), automotive glass insulation film.
Functional Coating Material
Wear-resistant and anti-oxidation coatings:
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);
Bioceramic modification:
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 Materials
Neutron absorbers:
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
Titanium-based alloy strengthening:
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.
