Preparation of nanometer cuprous oxide using sodium sulfite to reduce copper sulfate by microwave at standard atmospheric pressure was researched. The effects of operating conditions, such as microwave power, reaction time, sodium sulfite amount and solution pH,on yield and quality of cuprous oxide were examined, And surface appearance and particle size of cuprous oxide were studied. The yield and purity of cuprous oxide was 95.3% and 97.2% ,respectively. The shape of cuprous oxide was approximate to sphericity and particle diameter was range of 400 nm to 900 nm. Its dispersibility was good.
