ABSTRACT:
The invention relates to a candoluminescent material, its preparation process and its use as a gas lamp mantle.
This condoluminescent material is constituted by a mixture of finely divided oxides brought into the form of a netting identical to a textile, wherein it comprises 75 to 90 molar % of zirconium oxide ZrO.sub.2, 10 to 25 molar % of calcium oxide CaO, 0 to 5% of aluminum oxide and/or magnesium oxide and 0 to 1% in all of one or more oxides chosen from the group including iron oxide, manganese oxide, praseodymium oxide and cerium oxide.
It is prepared by impregnating a combustible textile with a solution of zirconium and calcium salts, optionally containing aluminum, aluminum, iron, manganese, praseodymium and/or cerium salts and then subjecting the impregnated textile to a combustion process in order to eliminate the textile and transform the salts into oxides.
