Entropy engineering in inorganic non-metallic glass

Advances in developing high entropy alloys and ceramics with improved physical properties have greatly broadened their application field from aerospace industry, public transportation to nuclear plants. In this review, we describe the concept of entropy engineering as applicable to inorganic non-metallic glasses, especially for tailoring and enhancing their mechanical, electrical, and optical properties. We also present opportunities and challenges in calculating entropy of inorganic non-metallic glass systems, correlating entropy to glass formation, and in developing functional inorganic non-metallic glasses via the entropy concept.
