With this technique, a special crystalline oxide comprising phosphorus, sulfur, and zirconium can be produced. This crystalline oxide has two separate mechanisms of negative thermal expansion. This material is also the first to exhibit this property, and its application may help prevent damage to composite materials, like computer chip components, that experience sudden temperature changes.
Upon heating, most of the materials tend to expand as the atoms get separated. The coefficient of thermal expansion (CTE) is used to measure the expansibility of materials under heat. A majority of the existing industry-grade materials have a positive CTE, which negatively impacts their performance when subje
