Abstract

L'invention concerne un procédé de préparation de silicate d'un élément choisi parmi les alcalins, alcalino-terreux ou terre rare, comprenant une réaction entre de la silice et un sulfate dudit élément dans un réacteur équipé d'au moins un brûleur immergé dans une masse en fusion, ledit brûleur immergé étant alimenté par un gaz comprenant de l'oxygène, un excès de combustible réducteur étant introduit dans le réacteur par rapport à l'oxygène effectivement consommé. Le procédé permet le déroulement de la réaction de façon satisfaisante et à relativement basse température.The invention relates to a process for preparing silicate of an element selected from alkali, alkaline earth or rare earth, comprising a reaction between silica and a sulfate of said element in a reactor equipped with at least one burner immersed in a molten mass, said submerged burner being supplied with a gas comprising oxygen, an excess of reducing fuel being introduced into the reactor relative to the oxygen actually consumed. The process allows the reaction to proceed satisfactorily and at relatively low temperature.
