It is also used as a shunt over polysilicon lines to increase their conductivity and increase signal speed. Further, it acts as a barrier layer between silicon and other metals. In addition to this, it is used in microelectro mechanical systems and for oxidation-resistant coatings. It is also employed as a replacement for earlier tungsten films.","specialNotes":null,"specialNotesProduct":false,"sds":"public/sds/WSi2.pdf","smiles":null,"inchi":null,"inchiKey":null,"molecularWeight":null,"iupac":null,"eccn":null,"hts":null,"atomicNumber":null,"atomicWeight":"240.01 g/mol","meltingPoint":"2160 °C","boilingPoint":null,"density":"9.3 g/cm³","crystalStructure":"Tetragonal","colorAppearance":"Blue-gray metallic powder","thermalConductivity":null,"electricalResistivity":"30-70 µΩ·cm","coefficientOfExpansion":"6.25 x 10^-6 /K","electronegativity":null,"neutronCrossSection":null,"electronConfiguration":null,"createdAt":"2020-05-19T14:34:39.000Z","updatedAt":"2026-04-28T21:40:39.884Z","deleted":false,"deletedAt":null,"userChangedById":null,"customContent":null,"displayFormula":null,"bottomText":null,"isAiData":true,"isHazmatAsPowder":false,"hazmatAsPowder":null,"tags":[{"id":137,"name":"Silicide","link":"silicide_chemical","type":"chemical"},{"id":279,"name":"Refractory Material","link":"refractory_material_chemical","type":"chemical"},{"id":296,"name":"Specialty Inorganics","link":"specialty_inorganics_chemical","type":"chemical"},{"id":419,"name":"Refractory Metals and Compounds","link":"refractory_chemicals","type":"chemical"}]},"userChangedBy":null,"ProductPrice":[{"id":189885,"productId":6089,"price":335,"quantity":1,"um":"pc","locked":false,"isShow":true,"createdAt":"2023-03-29T15:48:34.000Z","updatedAt":"2023-03-29T15:48:34.000Z","bulkAvailable":null,"bulkAvailability":false,"packaging":null,"customerId":null,"type":"default","version":1,"quoteId":null}],"Vendor":[],"tags":[],"favorites":[],"attachments":[]}
