· Na1 Co1 O2

Sodium cobalt oxide (NaCoO₂) is a layered oxide semiconductor belonging to the family of alkali metal transition metal oxides, characterized by a two-dimensional crystal structure similar to graphene-based materials. This compound is primarily investigated in research contexts for thermoelectric energy conversion applications, where its ability to generate electrical voltage from thermal gradients makes it valuable for waste heat recovery and power generation systems. NaCoO₂ is notable for its relatively high thermoelectric figure of merit compared to conventional materials and offers potential advantages in solid-state energy harvesting, particularly in applications requiring materials that are more thermally stable or earth-abundant than traditional bismuth-tellurium based thermoelectrics.

Export Control

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.
