CoSi2
metal· CoSi2
Cobalt disilicide (CoSi₂) is an intermetallic compound combining cobalt and silicon, belonging to the family of transition metal silicides. It is primarily used in semiconductor and microelectronic applications as a contact material and silicide layer, where its low electrical resistivity and compatibility with silicon processing make it valuable for reducing contact resistance in integrated circuits. CoSi₂ is also explored in high-temperature structural applications and thermoelectric devices due to its thermal stability and metallic bonding characteristics, offering advantages over pure metals in scenarios requiring both electrical conductivity and resistance to oxidation.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
