Ceramics and compounds Flashcards
Ceramics definition
made from non-metal solids
Properties of ceramics
excellent insulators of heat and electricity, high melting points, brittle, stiff
Examples of ceramics
glass, borosilicate glass, clay
How is glass made and its uses
heat sand + sodium carbonate + limestone = drinking glasses
How is borosilicate glass made and its uses
heat sand with boron trioxide = beaker, boiling tubes
How is clay made and its uses
heat wet clay in a furnace = pottery and bricks
Composites definition
mixture of a reinforcement and a matrix (binder)
Composites examples
wood, fiberglass, reinforced concrete. carbon fibre
Reinforcement and matrix of wood
R - cellulose, M - lignin
Reinforcement and matrix of fibreglass
R - glass fibre , M - resin
Reinforcement and matrix of reinforced concrete
R - steel and gravel , M - cement and sand mix
Reinforcement and matrix of carbon fibre
R - carbon nanotubes, M - polymer
