Abstract: Nanometer BaTiO₃and CuO powders were prepared by means of mechanophysical solid phase effects and powder metallurgy technology. A capacitive-type gas-sensitive element was made from those two powders, the results of gas-sensitive characteristics indicate that the element has good sensitivity to CO₂ gas. XRD and SEM analyses show that the element is just a homogeneous functional composite which is made from two phases by simply mechanical mixing.
