PRODUCTION OF A GAS-TIGHT, CRYSTALLINE MULLITE LAYER BY USING A THERMAL SPRAYING METHOD

The invention relates to a method for producing a tight crystalline mullite layer on a metallic and/or ceramic substrate by using the plasma spraying technique. To this end, a sol containing mullite precursors with a proportion of 2 to 25% by weight with regard to the oxides (3 Al2O3/2 SiO2) is used...
