Innovative Applications for Ceramic Materials

8:30 to 9:25 a.m.

Ultrahigh Temperature Ceramics for Extreme Environmental Applications

Speaker: Sylvia M. Johnson, Chief Materials Technologist in the Entry Vehicles and Systems Division, NASA Ames Research Center


Ultra high temperature ceramics (UHTCs) which includes the diborides of hafnium and zirconium have been known for a long time but over the last decade have seen a resurgence in research and development interest. There is particular interest in these materials for aerospace applications especially leading edges for entry vehicles. Theses materials are refractory and have attractive thermal properties; however, they are brittle and oxidize. Efforts to improve these properties are underway in many institutions. This talk will give some background on these materials and describe the application. The majority of the talk will discuss progress being made towards improving the mechanical and oxidation resistance properties, and point out the needs for further development.

9:30 to 10:25 a.m.

Bioengineering Soft Tissue with Ceramics

Speaker: Steve Jung, Senior Research & Development Engineer, MO-SCI Corporation


For much of the last 40 years, a hydroxyapatite based material or a bioactive glass that formed hydroxyapatite in-vivo was thought to be the ideal material for an orthopedic implant. Forming an appropriate end material in-vitro or in-vivo and studying the material’s ability to stimulate bone cells were the main areas of study. A new way of looking at regenerative materials is not just focusing on bone specific criteria, but also understanding the role soft tissue plays in the healing process. Connective tissue heals in a similar fashion; therefore understanding how to stimulate soft tissue growth (i.e. angiogenesis) with implant materials can be used to enhance healing in both hard and soft tissue applications.

10:45 to 11:40 a.m.

Advances in Glass Strength and Its Impact on Society

Speaker: Louis Mattos Jr., Senior Scientist, The Coca-Cola Company


Glass is prized for its ability to transmit light, be formed into miraculous shapes, and resist chemical corrosion. But today’s commercial glass fails to tap 99.5% of its theoretical strength and has one major flaw-it breaks. The vision of the Usable Glass Strength Coalition is to bridge the gap between the laboratory strength of glass and the usable commercial strength of glass, enabling dramatic innovations in design and sustainability. We will discuss the challenge and promise of forming a pre-competitive research coalition of industry, university and government agencies to support a fundamental research agenda to significantly improve the usable strength of glass.

1:00 to 1:55 p.m.

Ceramic Applications in the Automotive Industry

Speaker: Michael J. Hoffmann, Professor and Head of the Institute of Ceramics for Mechanical Engineering, Karlsruhe Institute of Technology (KIT)


Ceramic materials are widely used in automotive industry as structural or functional components such as pump seals, catalyst supports, particulate filters, spark plugs, sensors or piezoelectric actuators. Many other ceramic parts had been developed in the past, but never used in mass production. Reasons are often due to high costs, insufficient reliability or only minor benefits for the performance of the entire system. To open new markets for ceramic components in automotive industry, feasibility studies are required and the development of prototypes to demonstrate the potential of an enhanced efficiency. However, sometimes legislation is the driver for new products. Potential uses of engineering ceramics as local strengthening of light weight metal parts with porous ceramic performs or corrosive and tribologically highly stressed pump components will be covered. The current status of piezoelectric actuators for fuel injection systems and PTC heaters as well as the challenges for alternative materials to lead containing compounds will be discussed.


2:00 to 2:55 p.m.

Innovative “Multi-Use” Technologies and National Laboratories-Medical Initiatives from the Nuclear Community
Speaker: George Wicks, Consulting Scientist, Savannah River National Lab


The nuclear complex in the DOE system has made many significant contributions through its national laboratories to areas of national security, environmental remediation, waste management and energy, as well as many other uses, for more than a half century of operations. During this time period, creative and innovative technologies have been developed and successfully applied within the complex. Many of these technologies also have applicability to the commercial sector and some from industry have referred to the National Laboratories as a “gold mine” of new technologies needing commercialization. Discussed will be one group of recent initiatives between SRNL and the GA Health Sciences University, using “multi-use technologies” from the nuclear complex, that are being tailored for potential uses in the medical field, with examples in digital imaging, robotics, sensor technologies, microbiology and advanced ceramics and other materials.
