Préparation de la spray-pyrolyse d’un polymère précéramique non oxyde
Preparation for the spray-pyrolysis of a non-oxide preceramic polymer. This polymer will first be turned into a mist, then transported into the furnace by a carrier gas. Here, the polymer will undergo thermal decomposition, allowing the ceramic minerals to be recombined and recovered in the form of powder (the organic matter is trapped in the furnace by a cold bath of liquid nitrogen). This powder is made up of silicon, methane and nitrogen. This very fine microstructure (less than 100 nanometres) has excellent mechanical strength, which facilitates, during the next stage, the sintering of large ceramic parts.
