METHOD FOR PRODUCING SURFACE-TREATED ZINC OXIDE PARTICLE

This method for producing a surface-treated zinc oxide particle includes a first step for determining whether or not the specific surface area S (unit: m2/g) of the zinc oxide particle, the sodium content M (unit: mg/kg) of the zinc oxide particle, and the conductivity σ (unit: μS/cm) of a slurry pr...
