ceramics Flashcards
ceramic def
inorganic, non metallic solids
ceramic example
pottery and bricks (made from wet clay moulded and heated in furnace)
glass
soda lime glass
- most common glass
- combo of limestone, sodium carbonate and sand all heated
thermosoftening polymers
monomers that don’t allow crosslinks to form between chains / weak intermolecular forces
thermosetting polymers
allow cross links to form between chains
low dens poly(ethene)
moderate temp + high pres + catalyst
( in bonding of monomers)
high density poly(ethene)
lower temp + lower pres + different catalyst
composites def
made by embedding a material known as the reinforcement into the matrix
composite examples
concrete - matrix - cement
reinforcement - combo of sand and gravel
carbon fibre - polymer reinforced with carbon fibres/ nanotubes
fibreglass - polymer reinforced with glass fibres
polymer properties determining factors

conditions its made in
borosilicate
- made from coming boron trioxide with sand and heating to a higher temp
- commonly used in chemical glassware and kitchenware
glass
soda lime
