Abstract. A novel process was developed to produce spherical copper powder for multilayer ceramic capacitors (MLCC). Spherical ultrafine cuprous oxide (Cu 2 O) powder was prepared by glucose reduction of Cu(OH) 2.The Cu 2 O particles were coated by Mg(OH) 2 and reduced to metallic copper particles. At last, the copper particles were densified by high-temperature heat treatment.
