Let's Work Together

  • 3M Technical Ceramics boasts a broad portfolio of advanced ceramic materials and components designed to operate in harsh environments, help meet increasing regulatory requirements and perform in demanding applications.

  • High-quality materials and precision manufacturing help ensure the reliability and longevity of 3M™ Cathodes and Electron Guns for long-range communication systems.

  • 3M™ Ceramic Sand Screens resist abrasion and erosion better than metal screens, enhancing the productivity and efficiency of oil and gas operations.

  • Made of electrically conductive advanced ceramic composites and available with cavities or with a laser-treated surface, 3M™ Evaporation Boats are engineered for long life, high efficiency and performance in metallizing applications.

  • Embedded diamonds enhance friction to transmit higher loads while enabling more compact automotive engines, wind turbines and more. They reliably transmit up to 4x higher torques than conventional systems, so you can downsize without downgrading performance.

  • 3M Technical Ceramics high-purity fused silica flours, grains and shell systems help investment casting foundries produce highly accurate molds more quickly. 3M Technical Ceramics also offers fused silica shapes for demanding glass melting and metalforming operations.

  • 3M™ Stable Isotopes are optimized materials for critical applications in the nuclear and semiconductor industries. With enrichment to levels exceeding 99% isotopic purity and the ability to custom-engineer products, we can help you push the boundaries of performance, purity and consistency.

  • Engineered for outstanding shock absorption and high load capacity, 3M™ Thrust Bearings help improve the reliability of drilling motors and electric submersible pumps in the challenging environments of oil and gas production.
