Measuring the Thermal Expansion Coefficient of Ultrastable Materials with 10⁻⁹ K⁻¹ Uncertainty

Null-thermal expansion coefficient LAS-nSiC composite by slip-casting

“…Zerodur, Clearceram, Nexcera and Utralow Expansion Glass (ULE) are currently commercial materials used for this purpose [4] in the market but they have very similar drawbacks since they are very brittle which limits their applications to a large degree.…”
