The inventors of the present invention have extensively studied to find out the differential calcination conditions for production of stock material, reaching the fourth invention. The cerium-based abrasive was prepared from each of the above stock materials, and evaluated for grindability and scratches for the finished conditions of the ground surface for the comprehensive evaluation. A stock material for cerium-based abrasives, produced by the method according to claim Process for durable sol-gel produced alumina-based ceramics abrasive grain and abrasive products. Kimura and A. The oxide of rare earth then undergoes a crushing step to produce the agglomerate oxide of FIG. Cerium oxide CeO 2 is a promising material that has potential for use in a number of applications, such as resistive-type oxygen sensors and solid oxide fuel cells. Hahn, J. For this method, the carbonate of rare earth is first prepared.

    Cerium oxide (CeO2) is a promising material that has potential for use in a the sintering behavior of hydrothermal synthesized nano-size CeO2 powders and.
    Aozasa, J. As a result, the particles are sintered at relatively low temperature during the calcination process, because of lack of the causes for retarding the sintering, e.

    In particular, the abrasive from a stock material having an LOI of 5.

    Inoue, T. The slurry is sufficiently viscous for the cohesive force which bounds the carbonate particles to each other, deteriorating crushing efficiency and making it difficult to completely crush them into the fine particles.

    Roasting at such a relatively low temperature level can control abnormal growth of the particles for the cerium-based abrasive which can give a high-quality surface free of scratches. The partial calcination process for the present invention stops calcination before the carbonate is completely converted into the oxide, leaving a mixture of the carbonate and oxide for the stock material.

    WOA1 en. The carbonate of rare earth, similar to that for 24th Embodiment, was calcined in the same manner as in 24th Embodiment except under different conditions with respect to temperature and time, to prepare the stock materials.

    They are now sustaining the following phenomena as the reasons why the carbonate and oxide of rare earth need roasting at high temperature:.

    this, Mg-CeO2 composites were produced by powder metallurgy, with Keywords: Magnesium matrix composites, reinforcement of cerium.

    Cerium monosulfide (CeS) powder was synthesized by the reduction of Ce2S3 . composite oxide-metal powders for subsequent densification via sintering or.

    On the other hand, it is pointed out that the cerium-based abrasive produced from the oxide of rare-earth as the stock material tends to leave behind fine scratches on the ground surface, although excellent in grindability.

    EAB1 en. For this method, the carbonate and oxide of rare earth are first prepared.

    It is not necessary to prepare two or more types of the crude materials, which makes this method very economical and high in productivity. CNB en.

    The stock material of the first aspect of the invention, or the one produced by the method of the second or third aspect of the invention gives the cerium-based abrasive excellent in grindability and leaving behind little scratches on the ground surface. The ground glass surface was then evaluated for grindability of the abrasive and finished conditions of the ground surface.

    The oxide of rare earth is produced by calcination of the carbonate of rare earth, as described earlier, and the carbonate as the stock material for the oxide contains coarse particles, as shown in FIG. Journal of Materials Synthesis and Processing.

    Averback, J. Each stock material was measured for LOI using a part of the stock materials thus obtained in a similar manner. These abrasives were evaluated for grindability and conditions of the surfaces ground by them by the procedures described earlier.

    2 thoughts on “Cerium metal powder sintering”

    1. The inventors of the present invention have investigated the processes of producing a cerium-based abrasive for each type of the stock material, noting that the abrasive will have different grinding characteristics by stock material, as discussed above.

    2. The stock material for abrasives obtained had an LOI of 0. The uneven fluorination should have adverse effects on the sintering process while the particles are being roasted.
