Cerium-terbium co-precipitate preparation method
The present invention discloses a cerium-terbium co-precipitate preparation method, and relates to a cerium-terbium co-precipitate. The preparation steps comprise: carrying out mixing blending on a qualified cerium liquid and a qualified terbium liquid according to a certain ratio, detecting whether the ratio meets the requirement, placing the obtained cerium and terbium mixed liquid into a precipitation reaction kettle, adding an appropriate amount of oxalic acid water to precipitate, placing into a product washing suction filtration box after completing the precipitating, washing with purified water, carrying out qualification detecting, draining, and finally placing into a roller kiln to burn so as to obtain the cerium terbium oxide. The obtained cerium-terbium co-precipitate of the present invention has characteristics of easy use, stable chemical property, and good luminescence effect.
