Very Low Thermal Expansion Coefficient Materials

Strain engineering in graphene by laser irradiation

“…26 We argue that it is the high values and difference in sign of the thermal expansion coefficients for the two materials that leads to strain relaxation upon heating. This is also corroborated by the fact that in the case of the silica substrate, where the expansion coefficient is an order of magnitude smaller than that of lithium niobate, 27 no strain relaxation is observed.…”

Microwave, Spark Plasma and Conventional Sintering to Obtain Controlled Thermal Expansion β‐Eucryptite Materials

“…Therefore, the usefulness of these thermal properties in the production of materials with null expansion [2] has a wide range of potential engineering applications, as photonic, electronic, aeronautical or structural applications [3,4]. β-eucryptite is the most negative thermal expansion phase in the lithium aluminosilicate ceramic system and, consequently, β-eucryptite has been thoroughly studied [5,6].…”

Solid-state synthesis of embedded single-crystal metal oxide and phosphate nanoparticles and in situ crystallization

“…Pyrophophates A IV M 2 V O 7 , where the A IV cation includes Zr, Ti, Mo, Re, W, Th, U, Pu, Ce, Hf, Pb, Sn, Ge, and Si; M V = P, V, or As, are known for their unusual high temperature behaviour. [13] Thermal expansion is a necessary consideration in a number of applications where increases and decreases in temperatures can affect physical dimensions, stability, integrity, and mechanical properties of materials. To the best of our knowledge, there are no dedicated reports of controlled metal-phosphate nanomaterial synthesis through organometallic syntheses and subsequent procedures.…”
