New Crystalline Oxide may Prevent Overheating of Composite Materials
Written by AZoMJan 6 2021
Researchers from the Tokyo Institute of Technology have recently produced an innovative material that exhibits special thermal expansion properties.

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

The technique employed by the researchers allows the synthesis of a special crystalline oxide that contains phosphorus, sulfur and zirconium and shows two separate mechanisms of negative thermal expansion.
This material is the first one to exhibit this property and its application might help prevent damaging of composite materials, like computer chip components, which experience sudden temperature variations.
A majority of the materials have the ability to expand upon heating, as the atoms move away from one another. The expansibility of the materials when heated is quantified by making use of the coefficient of thermal expansion (CTE). Most of the existing industry-

Scientists at Tokyo Institute of Technology recently synthesized a novel material that displays unique thermal expansion properties. The method used by the scientists enables the production of a unique crystalline oxide containing zirconium, sulfur, and phosphorus, that exhibits two distinct mechanisms of negative thermal expansion. This is the first known material to show this property and its application may help avoid damage to composite materials, such as computer chip components, facing unexpected temperature changes.
