The invention relates to a powder comprising more than 70% of glass-ceramic and / or refractory particles, a particle of said powder being classed in the fraction called “matrix” or in the fraction called “aggregate” according to whether it is smaller than, or equal to 100 μm, or bigger than 100 μm, respectively,the aggregate, representing more than 60% of the powder, comprising:more than 40% of particles of a glass-ceramic material having a crystallization rate of higher than 50% and a thermal expansion value, measured at 700° C., of less than 0.3%, called “glass-ceramic grains”;less than 35% of particles of a refractory material different from a glass-ceramic material, called “refractory grains”, the quantity of refractory grains being higher than 10% if the aggregate comprises more than 40% of glass-ceramic grains having a thermal expansion value, measured at 700° C., of less than or equal to 0.15%;the matrix, representing more than 10% of the powder, comprising:less than 30% of particles of a refractory material different from a glass-ceramic material, called “fine refractory particles”, the quantity of fine refractory particles being higher than 5% and preferably lower than 25%, if the quantity of glass-ceramic grains having a crystallization rate of lower than 75% is higher than 5%;and between 0.1% and 18% of particles of a heat-activatable binder;all of the percentages being weight percentages in relation to the weight of the powder.

The invention relates to a powder comprising more than 70% of refractory particles, in weight percent relative to the weight of the powder, a particle of said powder being classed in the fraction called “matrix” or in the fraction called “aggregate”, according to whether it is smaller than, or equal to 100 μm, or larger than 100 μm, respectively, said powder comprising, in weight percent relative to the weight of the powder: between 0.1% and 18% of particles of a heat-activatable binder, called “heat-activatable binder particles”; and more than 40% of refractory particles, called “ATZ particles”, having the following chemical composition, in weight percentages on the basis of the oxides of said ATZ particles: 10%≦Al2O3≦55%; 35%≦TiO2≦80%; 1%≦MgO+Cr2O3≦10%; 8%≦ZrO2≦20%; SiO2≦8%.

The invention aims at an aqueous ink for high-temperature electrochemical cell electrodes and / or electrolyte containing particles of at least one mineral filler, at least one binder, and at least one dispersant. It also concerns the electrode and the electrolyte using such an ink.

A composite material containing a matrix and a fibrous reinforcement, in particular a textile embedded in the matrix. The matrix includes a geopolymer of the poly(phospho-sialate) type having the following formula I: (1) (—P—O—Si—O—Al—O—)n in which n is greater than 2. The matrix further includes zirconium covalently bonded to the matrix, especially in the —ZrO form and / or in the —O—Zr—O form. The matrix has a melting temperature greater than 700° C., especially equal to or greater than 1200° C.

An interfacing element of a lock zone of a door of a motor vehicle. The interfacing element comprises: includes a support made of plastic material, intended to be attached to a lining of the door, the lining being made of plastic material and a reinforcing plate of the lock zone onto which a lock is intended to be fastened, the plate being integrated to the support by overmolding. The support is made of a material having a Young's modulus lower than that of the plastic material of the lining of the door, and a coefficient of elongation at break greater than that of the plastic material of the lining of the door. A sub-assembly of motor vehicle includes a lining of tailgate and an interfacing element fastened onto an outer face of the lining.
