A method for directly titrating and forming
ceramic microspheres through
gel casting of a track comprises the following steps: firstly,
processing a track disc with a plurality of semicircular tracks, pasting a heating belt on the surface of one side, opposite to the semicircular tracks, of the track disc, spraying hydrophobic
coating on the surfaces of the semicircular tracks, and
drying the hydrophobic
coating through the heating belt; then preparing
ceramic slurry; and finally, carrying out
titration forming, obliquely placing the track disc, enabling an included angle of 10-15 degrees to be formed between the track disc and the horizontal direction, enabling the semicircular tracks to face upwards, placing the
titration disc at the top end of the track disc, enabling a plurality of
titration needle cylinders of the titration disc to be respectively aligned with the top ends of the semicircular tracks, and then heating the track disc at 120-150 DEG C by using the heating belt, and then injecting the
ceramic slurry into the titration disc, so that ceramic
slurry liquid drops roll downwards on the semicircular track and are heated and cured into ceramic
microsphere blanks. The preparation method has the advantages of low process cost, few procedures and easiness in realization of automatic production, and the prepared ceramic microspheres are high in
sphericity and uniform in internal structure.
