“…where a T 0 ÀT 1 is the technical CTE, which is valid in the temperature range from T 0 to T 1 [values given in (°C)]; y 0 and y 1 are the lattice parameters, given in units of Å , at the respective temperatures T 0 and T 1 [18,19]. The technical CTEs for the cell parameter a are 3.9 9 10 -6 K -1 (measured between 25 and 497°C) and 9.2 9 10 -6 K -1 (measured between 25 and 988°C).…”

Strontium silicates are widely known as high thermal expansion materials, especially from glass ceramic sealing applications. However, the thermal expansion behavior of the pure crystalline phases is still unknown. Hence, SrSiO 3 and Sr 2 SiO 4 were characterized with dilatometry and high-temperature X-ray diffraction. The measured coefficients of thermal expansion (CTE) of Sr 2 SiO 4 are strongly anisotropic and depending on the crystallographic direction vary between 3.9 and 16.6 9 10 -6 K -1 . SrSiO 3 has a somewhat higher isotropy of thermal expansion than Sr 2 SiO 4 . The CTE in the respective crystallographic directions differs by only 1.9 9 10 -6 K -1 . The mean CTE is between 10.9 and 12.8 9 10 -6 K -1 for SrSiO 3 and Sr 2 SiO 4 , respectively. A comparison of the Srphases with Ba-and Ca-phases with the same stoichiometry is given with respect to the crystal structures and the CTE.

“…Initially test specimen is heated upto two degree Celsius more than room temperature and retained at that temperature for 30 minutes to achieve equilibrium state.For very long temperature range, heating rate generally used is around 3-5°C min -1 [11]. In this test procedure, heating rate of 0.12-0.14 °C min -1 is used as temperature range of investigation is from room temperature to 45°C.Applied voltage to heater is increased slowly to increase temperature of the specimen.…”
