A kind of preparation method of light porous aluminum phosphate-Zirconium silicate ceramic ball, it is characterised in that using following steps：（1）Zirconium silicate powder, alumina powder, biphosphate aluminium powder, frit powder are carried out dry-mixed in proportion；（2）It is granulated, shaping, cylindric base substrate is made；（3）After 70 DEG C of dry base substrates 5 hours, base substrate is put into inner bottom part as in the spherical alumina crucible of semicircle, 150 DEG C are heated to 5 DEG C/min speed and be incubated 2 hours under air atmosphere, 380 DEG C are heated to 10 20 DEG C/min speed and be incubated 1 hour again, then 680 DEG C are heated to 1 DEG C/min speed and is incubated 2 hours, finally 1150 DEG C are heated to 5 DEG C/min speed and be incubated 2 hours, room temperature then is naturally cooled to, that is, light porous aluminum phosphate-Zirconium silicate ceramic ball is made. |
