because I need to weigth and is wet inside its container, I will use it in an experiment of atomic absorption
Dear Ana,
The preparation of anhydrous Lanthanum chloride comprising non vacuum drying of Lanthanum chloride heptahydrate which comprises heating of Lanthanum chloride heptahydrate in hydrogen chloride atmosphere at 200-3000C. Prior art the preparation of anhydrous Cerium chloride comprising vacuum drying of Cerium chloride heptahydrate for 2 hrs at 60°C followed by for 2 hrs at 80°C and continuing for 12 hrs at 140°C results in the formation of lump, therefore, inefficient at industrial scale.

It prepared by heating a mixture of lanthanum(III) oxide and ammonium chloride at 200-250 °C: see the following reference.

May I know Dr Ana, which procedure you followed to obtain anhydrous Lanthanum chloride from hydrated one?
