  • Oxidizing fluid for the chemical-mechanical polishing of ceramic materials
    Patent number: 10655035
    Abstract: The present disclosure is directed to a fluid composition that can be used in chemical-mechanical polishing processes of inorganic material. The fluid composition can include at least one oxidizing agent and a multivalent cation component. Using the fluid composition during a chemical-mechanical polishing process can facilitate a relatively defect free material surface after polishing while achieving a suitable material removal rate.
    Type: Grant
