Abstract
Nano-sized ZnO powder was synthesized by a precursor process using zinc sulfate salt and aluminum sulfate salt as starting materials. Pulp and crystalline cellulose were used as precursor materials. The crystallization process, morphologies, and thermal decomposition were studied as a function of calcination temperatures and raw material compositions. The calcined powders were evaluated by SEM, XRD, TG-DTA, and volume resistivity. The volume resistivity of 1.5 × 105 Ω·cm was obtained by using 2.5 mol% Al2O3 doping. The particle size of 40 nm was obtained by selecting appropriate process conditions.
