Abstract

Zero thermal expansion and creep resistance are indispensable for precision instruments; however, they are usually overlooked. This work utilized ZrW₂O₈ to incorporate SiO₂ nanoparticles into the crystal during hydrothermal assembly to form a sandwich structure. The sandwich structure ZrW₂O₈-SiO₂ composites with SiO₂-nanocore achieved zero thermal expansion (α¯ = −0.008 × 10⁻⁶ °C⁻¹ [30–300 °C]) by cold sintering (190 °C, 350 MPa). Simultaneously, the composites exhibited creep resistance via densification research. Furthermore, the composites displayed better electromagnetic wave transparency in the frequency range of 2–18 GHz than pure SiO₂ ceramics. This approach can effectively solve the thermal expansion and creep problems of wave-transparent materials and provide a feasible method for the material fabrication.
