- the present inventors have found that it becomes difficult to accomplish this, and have arrived at the present invention.
- the present invention comprises a rare earth oxide containing fluorine (F) and at least cerium (Ce), lanthanum (La), praseodymium (Pr) and neodymium (Nd) as rare earth elements.
- the total rare earth oxide equivalent weight (hereinafter referred to as TREO) weight ratio of Sani ⁇ neodymium accounted for (Nd 2 0 Roh TREO) is 0.001 wt% to 5 wt 0/0 This is a certain ceramic abrasive.
- TREO refers to the total weight of each rare earth element contained in the target object when converted to a rare earth oxide (converted), and is determined by analyzing and calculating the composition of the target substance.
- TREO performs pretreatment such as dissolution and dilution on the sample as necessary, and then precipitates all rare earth elements as oxalate. Further, it can be determined by a method of filtering, drying, roasting to obtain a rare earth oxide and then measuring the mass.
- the weight ratio (hereinafter sometimes referred to as a content ratio) of oxidized neodymium in TREO is about 9%.
- the cerium-based abrasive according to the present invention has a very low content of hin neodymium.
- a cerium-based abrasive having a proportion of the weight of the hineomium acid in TREO within the above range had a higher polishing rate and had a property of less easily causing scratches.
- the polishing can be performed in a shorter time than in the case where the conventional cerium-based abrasive is used.

- the cerium-based abrasive according to the present invention is preferably one in which the ratio of the total weight of the rare earth oxides of cerium, lanthanum, praseodymium and neodymium to TREO is 97% by weight or more. This is because a high level, a high polishing speed, and a scratch generation preventing effect can be obtained more reliably. From the viewpoint that these effects can be more reliably obtained, the value of the ratio is more preferably 98% by weight or more, and more preferably 99% by weight or more. Preferred.
- the weight ratio of cerium oxide to TREO is 50% by weight to 90% by weight. Is preferred. This is because cerium oxide is the most abrasive substance among all rare earth oxides, and if the weight ratio is less than the lower limit, a sufficient polishing rate cannot be obtained. On the other hand, if it is attempted to exceed the upper limit, lanthanum must be sufficiently reduced in the raw material refining process, which increases labor and cost, and deteriorates production. For this reason, the ratio of cerium oxide to TREO by weight is more preferably 55% by weight to 85% by weight, and further preferably 60% by weight to 80% by weight.
- Weight ratio of the acid Ihirantan occupied in TREO is preferably a double amount% to 45 wt%.

- the fluorine content is more preferably from 1% by weight to 8% by weight, and more preferably from 2% by weight to 7% by weight, in that a higher effect is obtained for both the wounds.
- the molar ratio (F / (L a + P r)) of fluorine (F) contained in the cerium-based abrasive to lanthanum (La) and praseodymium (P r) contained therein is 0.2 to 3 is preferred. If it is less than the lower limit, hydroxyl-based substances will be generated during storage and polishing of cerium-based abrasives, especially during polishing. Abrasives in the state where hydroxides are formed have the disadvantage that the polishing speed (polishing force) is low. In addition, if hydroxides are easily formed during polishing, there is a problem that the polishing rate is reduced in a short time from the start of polishing.
- an abrasive whose molar ratio exceeds the upper limit has a disadvantage that the chemical action of fluorine during polishing is too strong and the polished surface obtained after polishing is roughened.
