They are often made from silicon with controlled impurities added to change the properties of the material for different applications.
Different uses of materials.
The substance used to make something is called a material.
It makes much more sense to classify materials according to the way we use them.
Semiconductors are primarily used in electronics including computing units and solar.
For example a chair can be made from metal and wood and plastic.
A school desk for example may be made from wood plastic or metal or a mixture of all three materials.
This short clip shows different materials such as metals wood and plastic in different forms.
Includes footage of natural materials being manipulated for human use and man made.
It shows the different ways in which each material can be used.
The following are common types of building material.
Materials and their uses.
Different kinds of wood rock metal paper plastic on the basis of their properties including hardness strength flexibility and magnetic behavior and to relate these properties to everyday uses of the materials.
Building material is material used for construction many naturally occurring substances such as clay rocks sand and wood even twigs and leaves have been used to construct buildings apart from naturally occurring materials many man made products are in use some more and some less synthetic.
These are some of the types of materials most commonly used.
Materials with different uses.
Semiconductor materials aren t exactly a conductor such as gold or a insulator such as glass but fall somewhere in between.
That gives us building materials such as iron and steel glass and wood energy materials from coal and gasoline to peat and uranium materials for transportation.
Each material can be used to make a range of different things.
A spoon can be made from plastic wood or metal.
Leather is a durable wrinkle resistant fabric and it can take on many different looks and feels based on the type of animal grade and treatment.
Knowledge of materials allows for comparison of everyday materials e g.
While cowhide is the most popular animal skin used for leather comprising about 65 percent of all leather produced almost any animal can be made into leather from crocodiles to pigs to stingrays.
It also shows that some objects may be made from different materials e g.
An object can be made out of different materials used together.
This includes traditional materials such as wood and newer materials that are designed to meet a variety of modern construction requirements.
