Overview
Titanium tetroxide (Ti4O7) sputtering targets are high-purity materials used in physical vapor deposition (PVD) processes to create thin films. These targets are critical in industries requiring precise, durable coatings, such as semiconductors and optics. Ti4O7 targets are valued for their stability and conductivity, making them ideal for advanced applications. The compound Ti4O7 is part of the Magnéli phase titanium oxides, known for their mixed valence states and unique electronic properties. These characteristics enable efficient sputtering performance, ensuring uniform film deposition with minimal defects.
Physical and Chemical Properties
Ti4O7 is a dark gray or black solid with a density of approximately 4.2 g/cm³. It exhibits high thermal stability and is insoluble in water, making it suitable for high-temperature processes. Its electrical conductivity is superior to other titanium oxides, which is advantageous for sputtering applications. The material's crystalline structure contributes to its durability and performance under ion bombardment during sputtering. Its chemical inertness ensures compatibility with various substrates, reducing contamination risks in thin film production.
Main Applications
Ti4O7 targets are primarily used in semiconductor fabrication for creating conductive or insulating layers. They are also employed in optical coatings, such as anti-reflective or protective films for lenses and displays. Additionally, these targets find use in research labs for developing advanced materials. In the aerospace and automotive sectors, Ti4O7 coatings enhance component durability and resistance to wear. The targets' versatility extends to solar panels and energy storage devices, where precise thin films improve efficiency and longevity.
Safety and Storage
Handling Ti4O7 targets requires precautions to avoid exposure to fine particles, which can irritate the skin or respiratory system. Use gloves and protective eyewear in a well-ventilated area or under inert gas conditions. Store targets in sealed containers with desiccants to prevent moisture absorption. Avoid contact with strong acids or oxidizers, which may react with the material. Proper storage in a dry, cool environment extends shelf life and maintains target integrity for optimal sputtering performance.
B2B Procurement Guide
When procuring Ti4O7 targets, prioritize suppliers with certified quality control (e.g., ISO 9001) and traceable material origins. Specify purity levels (≥99.9%), dimensions, and bonding requirements (e.g., backing plate compatibility). Request material test reports (MTRs) to verify composition and performance metrics. Bulk orders may negotiate pricing, but ensure consistent quality across batches. Evaluate lead times and supplier reliability, especially for time-sensitive projects. Consider post-purchase support, such as technical assistance for target installation or troubleshooting.
