Silicon tin alloys (Si-Sn) are binary alloys that combine silicon (Si) and tin (Sn) to form materials with unique electronic, thermal and mechanical properties. These alloys are particularly valuable in advanced applications such as energy storage, electronics and materials engineering.
VIMATERIAL offers a wide range of silicon alloy materials.
Composition: Silicon tin alloy can be customised with different silicon and tin ratios depending on the intended application.
Electrical conductivity: Tin has good electrical conductivity, while silicon has semiconducting properties that make the alloy suitable for electronic applications.
Thermal Stability: Silicon enhances the alloy’s thermal resistance, while tin adds ductility and ease of processing.
High specific capacity: In energy storage applications, especially for lithium-ion batteries, both silicon and tin offer high lithium-ion storage capacity.
Corrosion resistance: Tin has oxidation and corrosion resistance, enhancing the durability of the alloy.
Lithium-ion batteries: Anode Material: Si-Sn alloy has been developed as an advanced anode material due to its high lithium storage capacity and cycling stability. It has the potential to replace conventional graphite anodes in high energy density batteries.
Semiconductors: New semiconductor materials for the development of microelectronics, especially in devices requiring high thermal and mechanical stability.
Sputtering targets: Silicon tin alloy sputtering targets are used in thin-film deposition processes to form coatings in electronic, optical and photovoltaic devices.
Alloying agents: Used as a component in other alloys to improve specific properties such as strength, corrosion resistance or electrical conductivity.
Coatings and Films: Silicon tin alloy films are used as protective coatings for optoelectronics and high-temperature applications.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
