Controllable Thermal Expansion in In_2-xFe_xMo_xO₁₂

Abstract:

The structural and thermal expansion properties of solid solutions In_2-xFe_xMo₃O₁₂ have been characterized using X-ray diffraction. The lattice parameters decrease linearly with increasing Fe content at room temperature. All compounds exhibit monoclinic structure at room temperature, and transform to orthorhombic phase upon heating. Monoclinic In_2-xFe_xMo₃O₁₂ (x = 0.3, 1.0 and 1.3) possess strong positive thermal expansion, while the linear thermal expansion coefficient of orthorhombic phase varies from zero/near-zero to positive with increasing Fe³⁺ content.
