Yttrium Silicide particles are yttrium silicide compounds, gray or black in color, with high melting point, high hardness, good chemical stability and excellent oxidation resistance, etc. They can be prepared by melting method, etc., and are valuable in high temperature structural materials and other fields.
Properties
Chemical Formula: YSi₂
Appearance: usually in gray or black granular form.
High melting point: Yttrium Silicide has a high melting point, generally above 2000°C. This characteristic enables it to remain solid at high temperatures, showing excellent thermal stability, and can be used in scenarios where high temperature resistance is required.
High hardness: its high hardness, with good wear resistance, in mechanical moving parts, cutting tools and other applications that require resistance to wear and tear has an advantage, can effectively extend the service life of parts.
Good chemical stability: At room temperature, Yttrium Silicide shows good resistance to most acids, alkalis and other chemicals, and is not easy to have chemical reactions, thus ensuring its stability and reliability in different chemical environments.
Excellent oxidation resistance: Under high temperature conditions, YSi₂ is able to form a layer of dense oxidized film, preventing oxygen from further contacting with the internal materials and effectively preventing the oxidation reaction from continuing, so that it can still maintain good performance in high temperature oxidized environments.
Applications
High-temperature structural materials: With its high melting point, high hardness and excellent oxidation resistance, Yttrium Silicide particles can be added as a reinforcing phase to ceramics, metals and other matrix materials for the manufacture of high-temperature structural parts such as hot-end parts of aerospace engines, gas turbine blades, etc., which can significantly improve the material’s high-temperature strength and creep resistance to ensure that the parts are stable in extreme high-temperature environments. .
Wear-resistant materials: The high hardness of Yttrium Silicide particles makes them ideal additives for the preparation of wear-resistant coatings and wear-resistant composites. Adding them to coating materials or matrices can effectively improve the surface hardness and wear resistance of the materials. Applied to machining tools, molds, bearings and other wear-prone parts, they can extend their service life and reduce production costs.
Electronic materials: In the field of electronics, Yttrium Silicide particles can be used to manufacture high-temperature electronic device encapsulation materials, electrode materials and so on. Its good chemical and thermal stability can ensure the normal operation of electronic devices in high temperature and harsh chemical environment, and improve the reliability and service life of the devices.
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.
