ABSTRACT:
A heat-insulating material has a first phase with the stoichiometric composition of 0.1 to 10 mol-% M12O3, 0.1 to 10 mol-% Li2O, and as the remainder M22O3with possible impurities. M1 is selected from the elements lanthanum, neodymium, gadolinium, or a mixture thereof, and M2 is selected from the elements aluminum, gallium, iron, or a mixture thereof. The first phase is present in a magnetoplumbite structure.
