Abstract

L'invention se rapporte à un mélange de poudres de céramique au chromite de lanthane, qui est constitué essentiellement par 1 mole de LaCr1-xMxO3, où M représente un métal bivalent choisi dans le groupe du magnésium, du calcium et de mélanges de ceux-ci et x est compris entre 0,03 et 0,3; y moles de B2O3, où y est compris entre 0,005 et 0,04; et z moles de La2O3, où le rapport z/y est compris entre 1,1 et 3. Ce mélange est produit sous la forme de comprimés de poudre et il est fritté à des températures aussi basses que 1400 °C jusqu'à présenter une compacité presque totale.
