A new method of preparing titanium dioxide

THE INVENTION REFERS TO A METHOD FOR PREPARING CRYSTAL TITANIUM DIOXIDE, IN WHICH: A) THE SOLID TITANIUM DIOXIDE HYDRATION IS TREATED WITH A BASE, B) THE PRECIPITATE TREATED WITH THE BASE WILL ALSO BE TREATED WITH HYDROCLORHYDRIC ACID) THE PRECIPITATE TREATED WITH THE BASE AND WITH THE ACID IS NEUTRALIZED. IT HAS BEEN TAKEN INTO CONSIDERATION THAT THE USEFUL CRYSTAL CRYSTALS, A MORE APPROPRIATE CRYSTAL SIZE AND A CRYSTAL SIZE DISTRIBUTION AND THAT CHEMICALS CAN BE SAVED AND THE FINAL CONTENT OF THE HYDROCLORHYDIC ACID OF THE STAGE A) IS ADJUSTED THE ONE THAT IS USED NORMALLY, AROUND 8 TO 25 G / LITER, FOR THE MICROCRYSTAL TITANIUM DIOXIDE PRECIPITATION. WHERE THE NEUTRALIZATION OF STAGE C) CAN ALSO BE CARRIED OUT BY RAISING THE PH TO THE HIGHEST VALUE THAN NORMALLY, THEREFORE: THE VALUE AROUND 4.0 TO 6.0.
