Abstract:
A thermal spray method for the manufacture of a layer for a heat insulating coat of a material in powder form that consists of at least 80 mol % of zirconium silicate ZrSiO.sub.4 wherein a majority of powder particles have diameters in the range between 10 and 100 .mu.m, and wherein the particles are at least partially melted through a gas flow under reducing conditions and at a temperature greater than 2000.degree. C., the method comprising choosing method parameters, including a dwell time of the particles in a heat imparting medium, a temperature of the heat imparting medium and momentum that is transferred to the particles, in such a manner that the layer that is formed of the particles has a structure with lamellar elements, and using suitable gases or gas mixtures as reducing means for the liberation of gases containing silicon.
