摘要:
The invention concerns a method for preparing a porous inorganic material comprising at least the following steps: a) reacting a mixture comprising at least a precursor of the oxide of a metal X in solution and a precursor of the oxide of a metal Y at a temperature of between 30 and 70°C, X and Y being chosen, separately, from the group consisting of aluminium, cobalt, indium, molybdenum, nickel, silicon, titanium, zirconium, zinc, iron, copper, manganese, gallium, germanium, phosphorus, boron, vanadium, tin, lead, hafnium, niobium, yttrium, cerium, gadolinium, tantalum, tungsten, antimony, europium and neodymium; b) mixing the mixture obtained at the end of step a) at a temperature of between 80 and 150°C, the duration of mixing being adjusted to obtain a paste having a loss on ignition of between 20% by weight and 90% by weight after this step; c) shaping the porous inorganic material; steps a) and c) being carried out inside an extruder.
摘要:
The invention relates to a novel composite material comprising at least one crystallised hybrid organic-inorganic material shaped in the form of an extruded product using a binder formulation comprising at least one polymer binder, said material having a high crystallised organic-inorganic hybrid material content. The invention also relates to the method for the production of said material.
