Applications: Cerium Mischmetal used as additive in alloys, hydrogen storage material, making flint. Lanthanum Cerium Alloy are widely applied in steel foundries industry for making FeSiMg alloy and it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony.
Packing: Steel drum aerated with argon with inner sealed plastic bag, N.wt 50/200kg.
Storage: Keep Sealed With Argon Or Coating Paraffin Wax Or Mineral Oil, And Store In Dry And Cool Places.
