Production of high-flexural-strength corundum ceramics

Cover Page

Abstract


A new method was proposed to produce high-flexural-strength corundum ceramics from α-Al2O3 samples synthesized by heat treatment of boehmite AlOOH at 1300 °C for 5 h. It was shown that hydrothermal treatment of MDGA-grade hydrargillite at 200 °C in a 0.4 wt % magnesium acetate solution for 3 days gives finely crystalline boehmite, which is a feedstock for synthesizing corundum ceramics with a flexural strength of 400 MPa.
