    Application:

    Cerium oxide with small particle size is used as glass additive, automotive emission control catalyst, polishing powder, hydrogen storage material, thermoelectric material, cerium-tungsten electrode, ceramic capacitor, piezoelectric ceramics, cerium carbide abrasive, raw material of fuel cell, gasoline catalyst, some permanent magnetic materials, different alloy steels and non-ferrous metals.

    Lanthanum oxide with small particle size is mainly used for the production of precision optical glass and optical fiber. It is also used in the electronic industry for the preparation of ceramic capacitors and as the piezoelectric ceramic adulterants. It is also used as raw material for preparation of lanthanum boride and refining catalyst for oil production.

    Packaging standard: 5kg / 10kg / 20kg packed in the double layer plastic bag, which is packed in the carton outside. The unit weight is 20 kg. The cartons will be packed on a pallet, with the unit weight of 1000 kg.

    It can also be packaged according to customer requirements.
