Cerium based abrasive material, raw material thereof and method for their preparation |
| abstract |
This invention provides a raw material for cerium based abrasive material, characterized in that it comprises a carbonate of a cerium base rare earth element and an oxide of a cerium base rare earth element and has a loss on ignition in the case of heating at 1000 DEG C for 1 hr of 0.5 to 25% on the basis of dry weight. The raw material is prepared by calcining a carbonate of a cerium base rare earth element at a specific temperature, to thereby convert a part of the carbonate of a cerium base rare earth element to an oxide of a cerium base rare earth element. The raw material can be sintered at a relatively low roasting temperature and thus is free from the occurrence of an extraordinarily grown grain. |
