SILICON NITRIDE: AN OVERVIEW

Silicon nitride (Si3N4) was first prepared in 1857 and was little more than a chemical curiosity. However, as its benefits became known, the compound began to be used across multiple industries in the late 1940s. Today, it’s a key component in electronics, turbomachinery, bearings, and even orbital satellites. In this article, we review the history of silicon nitride, key properties, and the top applications for this material.
