  • Patent number: 9308579
    Abstract: This invention publishes a method to prepare CaO-based ceramic cores used in investment casting applications. This method claims to use the rare earth oxide to coat the CaO core surface; later the coated cores are shaped then sintered to get the final products. CaO based core was made by 5˜15 wt % plasticizer, 0.001˜20 wt % mineralizer and the rare earth-coated CaO powders to balance for total 100%. This preparation method can solve the CaO core water absorption problems during core manufacturing, shipping and storage process while improve the core chemical inertness and mechanical properties.
