Development of polymer-derived ceramic sealing components

As industries increasingly prioritize sustainability and safety, the demand for alternatives to hazardous and polluting materials has grown. This research focuses on replacing tar-pitch, traditionally used in sealing components, with a safer, high-performance ceramic matrix. By leveraging ceramic precursors and polymer-derived ceramics (PDCs), the study aims to develop a robust and easily formable matrix suitable for applications such as water-handling machinery, including pumps. The choice of silicone resin in powder form allows for efficient dry forming, offering both simplicity and speed in manufacturing. Additionally, the new material can be processed at lower pyrolysis temperatures, providing economic advantages. A key focus of the study is the tribological performance of the material, specifically minimizing the coefficient of friction to prevent abrasion within the machinery. Mechanical performance and residual porosity have been also objective of the study. This research addresses both environmental concerns and operational demands, offering a promising alternative for industrial sealing components.
