Greek word Keramikos which means “Burnt Stuff” indicating that desired properties of these materials are normally achieved through a high temperature treatment.. Leaders in Engineered Ceramics As the world’s largest manufacturer of engineered ceramics, CoorsTek provides innovative ESD-safe ceramic components for semiconductor technology leaders around MATPrimary involvement in ceramics Advanced/engineering ceramics nergy/environmental ceramicsefractory ceramics Structural clay products Whitewares/stoneware/pottery products Vendor/supplier Raw mate Formations and linkages. What are polymers?. Alkene. molecules have the ability to add onto one another and produce large molecules these are polymers. . Therefore what are monomers?. The process of these large molecules forming is termed addition polymerisation.. AND . POLYMERIZATION. By. Dr Rashid Hassan. Assistant Professor. RIHS. ISLAMABAD. 1. POLYMER. Poly = Many mer = Units. I.e. a material made up of many units.. Properly defined as:. Chemical compound composed of large organic molecules formed by the union of many repeating small monomer units.. Hand Building Techniques . Coiled Pottery . - . One of the oldest ways of forming pottery. Long . strands/snakes/coils . of clay which are laid on top of each other and joined through . slipping and scoring. . Ceramics Vocabulary. 1. . Ceramics. – an object made from clay. 2. . . Plastic. – clay that is soft and easy to work with. 3. . . Leatherhard. – clay that is slightly dried and holds its shape. They are distiguished by its bonding which is ionic or covalent bonding. High elastic modulus and hardness. High melting point. Low thermal expansion. Good chemical resistance. Brittle. Thermal insulators. Onur Yalçınkılıç 1107130025. Aydın Karaömer 1107130010.
