A METHOD FOR MAKING COMPOUNDS BASED ON SILICATE, A DEVICE FOR IMPLEMENTING THE SAME AND A METHOD FOR MAKING GLASS

摘要

The invention concerns a method for making compounds based on silicate(s) of alkaline such as Na, ?? and/or of alkaline-earth such as MgO, CaO and/or of rare earths such as Ce, optionally in the form of mixed silicates combining those, by converting silica and halides, in particular chloride(s), or sulphates or nitrates of said alkalis and/or said rare earths and/or said alkaline-earths, such as NaCl, KCl, ??????l4. The thermal input required forthe conversion is supplied, at least partly, by an immersed burner or burners. The invention also concerns an implementing device and the use thereof
