i) Glass What is glass? ‘Glass is a non-crystalline solid that is often transparent, brittle and chemically inert. (not chemically active)’ Major Components & Main Characteristics of Glass
Types of Glasses
ii) Ceramic What is ceramic? ‘Ceramics are mixtures of clay, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln.’ Major Components and Main Characteristics of Ceramic
Uses, Properties and Examples of Ceramics
iii) Composite Materials What are composite materials? ‘Composite material is a material made from two or more constituent materials with significantly different physical or chemical properties. When combined, the constituent components will produce a material with distinct and stronger properties than those of the individual components.’ a) Matrix Substance : The matrix is a continuous phase of the composite material. It provides cohesion and holds the reinforcement materials together. b) Reinforcement Substance : Reinforcement materials are dispersed throughout the matrix and is the main contributor for the enhanced properties of the composite.
Reinforced Concrete Reinforced concrete is a composite material composed of concrete and reinforcement steel bars embedded within the concrete. Superconductor Superconductor is a mixture of yttrium(III) carbonate, barium carbonate (BaCO3) and copper(II) (CuCO3) carbonate with are heated together in the presence of oxygen. Fibre Optic Fiber optics is a technology that uses thin strands of glass or plastic fibers to transmit data in the form of light signals over long distances.
Fibreglass Fiberglass, also spelled fibreglass, is a composite material made from fine fibers of glass embedded in a resin matrix. Photochromic Glass Photochromic glass is a type of glass that changes color in response to light exposure.
