COMPOUNDS OF THE METALS BERYLLIUM, MAGNESIUM, ALUMINIUM, CALCIUM, STRONTIUM, BARIUM, RADIUM, THORIUM, OR OF THE RARE-EARTH METALS

**Definition:** This place covers:

Compounds of beryllium, e.g. fluorides, oxides, hydroxides.

Compounds of magnesium, e.g. magnesia, hydroxide, carbonates, halides, nitrates, sulfates, sulfites.

Compounds of aluminium, e.g. carbonate, oxides, hydroxides, alkali metal aluminates, halides, nitrates, sulfides, sulfites, sulfates.

Compounds of calcium, strontium or barium, e.g. oxides, hydroxides, carbonates, halides, nitrates, sulfates, sulfites.

Compounds of radium.

Compounds of thorium.

Compounds of the rare earth metals, i.e. scandium, yttrium, lanthanum, lanthanides.

Synthesis, treatment or modification of any of the elements or compounds above by:

Forming shaped metal compounds covered by C01F and the shaped products, per se, e.g. granules.

All compounds of Be, Mg, Al, Ca, Sr, Ba, Ra, Th or rare earth metals except those compounds which are classified in C01G because of application of the last appropriate place rule. So, in principle does this subclass comprise all Al-compounds with elements as such being part of C01B - C01D , e.g. Al 2 O 3 , Al(NO 3 ) 3 , Al 2 S 3 .
