Strain and Fracture of a Ceramic Based on Lanthanum Chromite

Strain and Fracture of a Ceramic Based on Lanthanum Chromite The bending behavior of a ceramic — a lanthanum chromite-based solid solution La1 – x CaxCrO3 (x = 0.025) doped with 5 – 40 wt.% Y2O3 — is studied in the temperature range of 20 – 1400°C. At 20°C the composition with 5 – 10 wt.% Y2O3 is strained inelastically and exhibits relatively superior mechanical properties in comparison to compositions containing 20 – 40 wt.% Y2O3. These compositions are prone to brittle fracture within the linear elastic strain. Based on the strain and fracture characteristics of lanthanum chromite at 20°C, its mechanical behavior at high temperatures is predicted. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

The bending behavior of a ceramic — a lanthanum chromite-based solid solution La1 – x CaxCrO3 (x = 0.025) doped with 5 – 40 wt.% Y2O3 — is studied in the temperature range of 20 – 1400°C. At 20°C the composition with 5 – 10 wt.% Y2O3 is strained inelastically and exhibits relatively superior mechanical properties in comparison to compositions containing 20 – 40 wt.% Y2O3. These compositions are prone to brittle fracture within the linear elastic strain. Based on the strain and fracture characteristics of lanthanum chromite at 20°C, its mechanical behavior at high temperatures is predicted.
