The control of thermal expansion and impedance of Al–Zr2(WO4)(PO4)2 nano-cermets for near-zero-strain Al alloy and fine electrical components

Low thermal expansion over a wide temperature range of Zr1-Fe V2-Mo O7 (0 ≤ x ≤ 0.9)

“…Negative thermal expansion (NTE) materials have attracted tremendous attention due to their potential applications in manufacturing zero thermal expansion devices and matching the coefficients of thermal expansion(CTE) between different materials [1][2][3]. However, some disadvantages of NTE materials limit their wide utilization, such as metastable structure [4,5], phase transition, hygroscopicity [6], anisotropy [7], etc. Plenty of investigations are focused on improving their properties, developing novel NTE materials.…”

Fabrication and characterization of ZrW2O8-Cf/E51 negative thermal expansion composite

“…The composites with negative expansion ceramics, oxides and ferroelectric ferromagnetic materials as the reinforcements and metals (Al, Cu, Ti, etc), ceramics and polymer as the matrix have been reported in the literature. Since Sleight's team [18] found zirconium tungstate (ZrW 2 O 8 , CTE is −8.7×10 −6 /°C) had negative CTEs in a wide temperature range, ZrW 2 O 8 particles had attracted more and more attention as a kind of thermal expansion regulating phase [19][20][21]. Through the study of phase transformation decomposition, researchers have found that ZrW 2 O 8 can be stable in service below 770°C and the decomposition temperature range is 780∼1108°C [22], which is an ideal negative expansion control phase.…”
