Ceramic powder, piezoelectric ceramic, piezoelectric element, and electronic equipment
A ceramic powder contains a metal oxide represented by the following general formula (1). The ceramic powder has a single perovskite-type crystal phase. The ceramic powder is composed of particles having an average equivalent circular diameter in the range of 100 nm or more and less than 1000 nm and has a ratio c1/a1 in the range of 1.000!<=c1/a1!<=1.010, wherein c1 and a1 denote the c-axis length and a-axis length, respectively, of unit cells of the perovskite-type metal oxide, c1 being greater than or equal to a1 (Ba1-xCax)[alpha](Ti1-y-zZryMnz)O3(0.9900!<=[alpha]!<=1.0100, 0.125!<=x!<=0.300, 0.020!<=y!<=0.095, 0.003!<=z!<=0.016).
