Hanna Kähäri

Title: **Hanna Kähäri: Innovator in Ceramic Composite Materials**

Introduction

Hanna Kähäri is a noted inventor based in Oulu, Finland. She has made significant contributions to the field of ceramic composite materials, holding two patents that showcase her innovative work.

Latest Patents

Hanna's latest patents involve a novel process for manufacturing ceramic-metal composite materials. This process begins by dissolving ceramic powder in water to create an aqueous solution. Metal powder, which possesses a multimodal particle size, is then mixed with this solution to form a powder containing ceramic that is precipitated on the metal particles' surfaces. Following this, the mixture is combined with additional ceramic powder of a smaller particle size, resulting in a powder mixture. A saturated aqueous solution of ceramic is added to this mixture to obtain an aqueous composition containing both ceramic and metal. This composition is then compressed to form a disc of ceramic-metal composite material, with the ceramic content ranging from 10 to 35 volume percent. Additionally, the patented process allows for the alternative manufacturing of ceramic-ceramic composite materials.
