Patent ID: 8901022

Claim:
A powder comprising more than 70% of refractory particles, as a percentage by weight in relation to the weight of the powder, said powder comprising, in percentages by weight in relation to the weight of the powder: from 0.1% to 18% of particles of a heat-activatable binder, referred to as “heat-activatable binder particles”, and more than 40% of refractory particles, referred to a “ATZ particles”, having the following chemical composition, in percentages by weight on the basis of the oxides of said ATZ particles: 10%≦Al 2 O 3 ≦55%, 35%≦TiO 2 ≦80%, 1%≦MgO+Cr 2 O 3 ≦10%, 8%≦ZrO 2 ≦20%, SiO 2 ≦8%.
