Fired setter ceramic substrate with protrusions on the surface and porous ceramics.

basic information

Improvement of "Debinding" Performance and Characteristics The workpieces produced in the firing process have diversified applications, and the quality of firing is required to be at a very high level. Among the process conditions that affect firing quality, "debinding performance and characteristics" are important, and various porous ceramic materials are being utilized creatively. In addition to these porous ceramic substrate technologies, using setter ceramics with "micro-convex porous ceramic processing" allows for space to be secured at the bottom of the fired workpieces, thereby improving debinding efficiency and performance.

Suppression of Shrinkage Deformation in Fired Workpieces One of the causes of dimensional deformation of workpieces during firing is the "contact state between the fired workpiece and the ceramic support plate." When the balance between the deformation forces applied to the workpiece during the firing process and the contact forces with the ceramic support plate is disrupted, issues such as "deformation and warping" occur, leading to results that do not meet the expected finished dimensions. By applying "micro-convex processing to the surface of the ceramic support plate," the contact with the workpiece becomes closer to point contact, making it less likely for the stress balance due to shrinkage during firing to be disrupted, which is expected to suppress shrinkage deformation. Ceramics for Setter With reduced contact with the fired items, deformation due to shrinkage during firing is suppressed. Suppression of Adhesion of Fired Workpieces Among the operational challenges in the firing process, "the detachment of workpieces from the setter after firing" significantly impacts production efficiency. Additionally, the potential for damage to the workpieces after firing is a major concern. By using ceramic support plates for setters that have undergone "micro-convex porous ceramic processing," the workpieces come closer to point contact, which is expected to facilitate "adhesion suppression," allowing for very smooth retrieval after firing. This is anticipated to improve the "operational efficiency of the firing process."
