Abstract
A multi-layer refractory structure is provided capable of withstanding high temperatures of the order of 2000.degree. C. to 2500.degree. C. for hundreds of hours. This structure comprises at least two layers, the first of which, subjected directly to said high temperatures and formed by a simple or composite metal oxide or a zirconate, has a thickness between about 1 mm and 4 mm and a specific gravity between about 2.2 and 4.8 and the second layer of which, which serves as support for said first layer, is of the same nature as this latter and has a thickness between about 5 mm and 12 mm and a specific gravity between about 2.2 and 4.2.
