Analysis and quantification of improvement in green manufacturing process of silicon nitride products

Abstract

Although green manufacturing is an important issue, not only energy consumption but also manufacturing quality is important for practical industries. In this report, the enhancement in product quality, are taken into account to quantify the process improvement. In quantifying the improvement, quality characteristics are categorized to 3 types to express real material requirements. As a result, it is said that the newly developed high-speed-reactive-sintering method to fabricate silicon nitride parts is far more energy efficient than the conventional method, because the process can improve material characteristics, shorten the processing time and reduce energy consumption throughput the total process.
