Title: Innovations in Ceramic Composite Materials by Inventor Jari Hannu

Introduction

Jari Hannu, an innovative inventor based in Oulu, Finland, has made a significant impact in the field of material science through his contributions to ceramic composite materials. With a total of three patents to his name, his work focuses on processes that enhance the manufacturing and functionality of these composites, particularly the integration of ceramic and metal components.

Latest Patents

Hannu's latest patents revolve around a groundbreaking process for manufacturing ceramic-metal composite materials. The process involves dissolving ceramic powder into water to create an aqueous solution of ceramic. By mixing metal powder with a multimodal particle size—where the largest particle size is one fourth of the minimum dimension of a device—this solution results in a powder that contains ceramic precipitated on the surface of the metal particles. The technique further includes combining this powder with additional ceramic powder of a particle size below 50 μm, creating a powder mixture. After adding a saturated aqueous solution of ceramic and compressing the resulting composition, a disc of ceramic-metal composite material is formed. The disc contains 10% to 35% volume of ceramic. Additionally, the process allows for the manufacture of ceramic-ceramic composite materials as an alternative.
