Negative thermal expansion material with reduced cost and density
A recently granted patent (Publication Number: US11970396B2) discloses a negative thermal expansion material with a unique composition represented by Zr2-aMaSxP2O12+d, where M is Sn and a is 0. This material exhibits a negative thermal expansion coefficient, making it suitable for various applications requiring controlled thermal expansion properties. Additionally, the patent claims a specific range for the value of x (0.4=x=0.48) to optimize the material's performance.
Furthermore, the patent describes the creation of composite materials by combining the negative thermal expansion material with metals or resin materials having positive thermal expansion coefficients. The method for producing the negative thermal expansion material involves hydrothermal treatment of a mixture containing specific compounds at controlled temperatures, followed by baking to form the desired material. By controlling the parameters during the production process, such as the temperature for baking and hydrothermal treatment, the properties of the material can be tailored to meet specific requirements for different applications. This innovation opens up possibilities for the development of advanced materials with tailored thermal expansion properties for use in various industries.
