摘要：A powder is disclosed having a coarse fraction representing more than 60% andless than 85% of the powder, as a weight percentage on the basis of the oxides, and thatis constituted of particles having a size greater than or equal to 50 μm, referred to as
“coarse particles”, the powder comprising at least 5% of coated grains having a sizegreater than or equal to 50 μm, as a weight percentage on the basis of the oxides of thepowder, and a fine fraction, forming the balance to 100% as a weight percentage on thebasis of the oxides, constituted of particles having a size of less than 50 μm, referred toas “matrix particles”. The powder can be applied in combustion chambers in which thetemperature may reach 1400° C.
