摘要：
The present invention relates to a powder comprising: a coarse fraction representing more than 60% and less than 85% of the powder, as a weight percentage on the basis of the oxides, and that is 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 size greater than or equal to 50 μm, as a weight percentage on the basis of the oxides of the powder, and - a fine fraction, forming the balance to 100% as a weight percentage on the basis of the oxides, constituted of particles having a size of less than 50 μm, referred to as "matrix particles". Application in combustion chambers in which the temperature may reach 1400°C.
