Ceramics Engineering of Technical & Industrial Ceramics

Superior Ceramic Engineering Assistance

At PremaTech Advanced Ceramics, we help you select the materials and shapes that best meet your specific requirements. Whether you're using technical ceramics materials or hard materials for applications in aerospace & defense, commercial, life sciences, medical, optics, R&D, power generation or semiconductor manufacturing, PremaTech has the experience and know-how to help you develop innovative and efficient uses of silicon carbides, silicon nitrides, alumina, zirconia, ultra-hard materials, boron nitride, ferrite or quartz.

  • Struggling with specifying the proper surface finish?
    We can help you understand the cost specification trade-offs.
  • Need an aspheric shape ground into your mirror?
    Don't settle for a “best-fit” sphere. We're able to grind aspheric shapes into mirrors 6" deep with diameters over 20".

Wherever there's a need for advanced ceramics, PremaTech has the ability to develop customized solutions for applications in aerospace & defense, commercial, life sciences, medical, optics, R&D, power generation and semiconductor manufacturing.

Our commitment to excellence in ceramics engineering is demonstrated by our ISO 9001:2008 Certification (Registration #951 07 4242), and by our dedication to best practices in meeting ITAR (International Traffic in Arms Regulations) and CCR (Central Contractor Registration) requirements.

Our Ceramics Engineering Team Helps You Determine The Proper Surface Finish?

Advanced ceramic materials are unique because they are susceptible to subsurface damage during the machining process. The same component can be machined by two different companies, both meeting the same "generic" dimensional and surface finish specifications, yet one part fails in its application. There are many considerations related to surface roughness that aerospace and defense professionals should understand to ensure that a component will be manufactured at a reasonable cost, delivered on-time, and have the ability to perform as designed. Various machining methods, such as diamond wheel grinding, lapping, and polishing greatly affect surface roughness. Metrology is also critical for verifying and confirming the final results.

Typical uses of ceramics within the aerospace and defense industries include:

  • Mirrors (Lasers, Telescopes)
  • Radomes
  • Gas Turbine Components (Shrouds, Vanes, Blades, Blisks)
  • Transparent Windows and Domes
  • Rocket Components
  • Nuclear Components
