Abstract
The invention discloses a manufacturing method for a cerium based abrasive material. The method comprises the steps of: 1) soaking a raw material of the cerium based abrasive material in a water solution, and conducting heating and crushing; 2) roasting the crushed raw material; and 3) crushing the roasted raw material. Specifically, the raw material of the cerium based abrasive material adopts a cerium based rare earth carbonate or a mixture of cerium rare earth carbonate and cerium rare earth oxide.
Description
Technical field
The present invention relates to a kind of manufacture method of cerium based abrasive material.
Background technology
Up to now, in the grinding step of implementing corresponding to the magnetic recording medium of high density recording and high-speed read-write, very high to the accuracy requirement of the smoothness of glass baseplate surface, if but the concentration of oversize particle in abrasive substance is high, easily cause being polished the generation of injurious surface mark, thereby can not meet the requirement of smoothness.Based on existing manufacture method, such as the wet processed of being undertaken by use ball mill, masher, and add the fluoridation that fluorine component carries out, can cause the abrasive substance of particulate when grinding easily adhere on the face of being polished and easily residue on the face of being polished, therefore there will be the bad clean problem of the face of being polished.
Summary of the invention
therefore, the object of the present invention is to provide a kind of concentration of oversize particle lower, can guarantee higher abrasive power and be polished the manufacture method of the good cerium based abrasive material of the detergency of face.
in order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
a manufacture method for cerium based abrasive material, comprises the steps:
1) raw material of cerium based abrasive material be impregnated in to the step that under the state of the aqueous solution, heating is pulverized; 2) step of the raw material after pulverizing being carried out to roasting; 3) by the step of the raw material crushing after roasting;
the raw material of wherein said cerium based abrasive material adopts the mixing raw material of cerium based rare earth carbonate or cerium based rare earth carbonate and cerium based rare earth oxide compound.
preferably, the Heating temperature of the aqueous solution of described step 1) is 60 ℃ ~ 100 ℃.
preferably, the Heating temperature of the aqueous solution of described step 1) is 80 ℃.
preferably, in described step 1) ~ 4) between do not comprise the step of case of wet attrition.
owing to having adopted technical scheme as above, the present invention has following beneficial effect:
make the concentration of oversize particle lower; Can guarantee higher abrasive power; Make the detergency of the face that is polished better.
