Sol-Gel Synthesis of MgO–Al2O3–ZrO2–SiO2 Coatings on Quartz Ceramics

In the work, the MgO–Al 2 O 3 –ZrO 2 –SiO 2 coatings on the surface of quartz ceramics were prepared by sol-gel method. The synthesized materials were examined by X-ray phase and electron microscopic analyses. It is shown that composite gels retain an amorphous structure after thermal treatment at 6...
