C12 Separator Powder Sheets are thin, flexible sheets comprised of specially processed, high-purity zirconium oxide (ZrO2) aluminum oxide (Al2O3), or magnesium oxide (MgO) particles. Separator Powder Sheets are an effective, low-cost solution for eliminating problems with sticking, cracking, and warping that make firing delicate green forms and sintering components challenging.
C12 SPS Sheets are comprised of high purity ceramic particles in a proprietary binder that is free of phthalates and engineered to burn out cleanly at low temperatures. A thin, highly uniform layer of inert refractory particles is deposited between the surface of the setter plate and the parts that are being fired. This inert layer of particles resists sintering, and provides a low friction surface that allows for shrinkage of green parts with minimal stress, sticking, and distortion. C12 SPS sheets are highly flexibile and conformal and can be easily used to line setter trays and 3D surfaces.
Lighter-grade Separator Powder Sheets are ideal for firing flat ceramic plates, SOFC's, tapecast ceramics, PZT/PLZT piezoceramics, and other delicate parts that require high surface quality and low distortion. Heavier-grade Separator Powder Sheets are also available for firing medium to larger sized technical ceramics with superior results.
