Most materials fall into one of three classes that are based on the atomic bonding forces of a particular material. 4 Magnetic Properties 2. 1 INTRODUCTION The word ceramic is derived from keramos, the Greek word for potter’s clay or ware made from clay and fired and can simply be interpreted as ‘pottery’. They are used primarily to enhance and/or channel the flux produced by an electric current. The manual describes several options for mounting fish. 02) physical properties have been investigated employing comprehensive characterization studies.
