Method for producing glass substrate for magnetic disk, and magnetic disk |
| abstract |
A method for producing a glass substrate for a magnetic disk by polishing a circular glass plate, which comprises a step of polishing the principal plane of the circular glass plate by using a slurry containing a CeO 2 crystal powder, the CeO 2 crystal powder being obtained in such a manner that a melt containing CeO 2 is quenched to obtain an amorphous material, and the amorphous material is subjected to heat treatment to obtain a CeO 2 crystals-precipitated amorphous material, which is subjected to acid treatment to separate and extract the CeO 2 crystal powder from the CeO 2 crystals-precipitated amorphous material. |
