What is soda lime glass made from ?
Sand
Sodium carbonate
Limestone
What is soda lime glass used for ?
Windows and bottles
What is the problem with soda lime glass ?
Low melting point which limits its usage
What is the other type of glass?
Borosilicate glass
What is borosilicate glass made from ?
Sand
Boron oxide
What do we use borosilicate glass for ?
Since it has a higher melting point it is often used for kitchenware or lab ware
What are examples of clay ceramics ?
Pottery
Bricks
What is clay ?
A mineral we find in the ground
How are clay cermanics made v
Shaping wet clay and then hearing in a furnace
What are composites ?
Two materials that have different properties combined to make a more useful material
What is the reinforcment?
Fibres or other materials that make up the bulk of a composite material
What is the reinforcement surrounded by ?
A matrix of binder material
What are the properties of composites ?
Strong
Water proof
Durable
Aesthetic reasons
What are the reinforcment and matrix of composite carbon fibre/ tubes ?
Reinforcement: carbon fibres/ nano tubes
Matrix: tough polymer
What is carbon fibre used for ?
Cars or in aircraft parts
What are the reinforcment and matrix of the composite Concrete ?
Reinforcement: mesh of steel cables
Matrix: concrete
What is reinforced concrete used for ?
To make buildings because it’s extremely strong
Why is reinforced concrete strong?
The material is strong when stretched because of the steel and strong when squashed because of the concrete
