Discuss the following with application and Properties:
Glass
- This is a hardwearing, abrasion-resistant material with excellent weathering properties.
- It is used for electrical insulators, laboratory equipment, and optical components in measuring instruments and, in the form of fibers, is used to reinforce plastics.
- It is made by melting together the naturally occurring materials: silica (sand), limestone (calcium carbonate) and soda (sodium carbonate).
Ceramic
- These are produced by baking naturally occurring clays at high temperatures after molding to shape.
- They are used for high – voltage insulators and high – temperature – resistant cutting tool tips.
Plastics
- Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.
- It is used in numerous packaging applications including containers, bottles, drums, trays, boxes, cups and vending packaging, baby products and protection packaging.
