Abstract
The use of a thermal spray method relates to the production of a layer (,) for a heat insulating coat of a material (,) in powder form. This material consists at least to,mol % of zirconium silicate ZrSiO,, in particular of the mineral zircon, and the majority of its powder particles (,) have diameters in the region between,and,&mgr;m. During the spraying on the particles are at least partially melted through in a gas flow (,) under reducing conditions and at a temperature greater than 20000° C. Method parameters, among others the dwell time of the particles in a heat imparting medium, in particular a plasma (,) or a flame, the temperature of the heat imparting medium and the momentum transferred to the particles, are chosen in such a manner that the layer (,) which is formed of the particles has a structure with lamellar elements (,). Suitable gases or gas mixtures, preferably hydrogen, are used as reducing means for the liberation of gases containing silicon, in particular silicon monoxide SiO; and/or a thermal liberation of gases containing silicon takes place as a result of a high temperature of the heat imparting medium.
