Abstract

L'invention concerne une unité destinée à être utilisée dans un four à atmosphère non contrôlée pour conduire une opération de synthèse de précurseurs en vue de former un produit de synthèse à hautes températures. Cette unité est constituée d'une cuve qui présente au moins une ouverture et qui est destinée à contenir les matériaux de l'opération de synthèse, ainsi que d'un matériau réducteur solide. Les matériaux de l'opération de synthèse sont séparés de l'atmosphère du four par la cuve ou par le matériau réducteur. L'unité convient particulièrement bien pour synthétiser LiFePO4 à partir de Fe2O3, Li2CO3, de noir de carbone et de précurseurs d'acide phosphorique.
