Which (for ceramic relevant) properties derive from the chemical bond?
Melting temperature
Mechanical resistance
Deformability
Surface energy
How much empty space is present in fcc?
26%
How much empty space is present in hcp?
What are the pauling rules?
The coordination number depends on the ratio of the the radii
In a stable structure the bond strength must be equal to the anion charge
corners rather than edges rather than faces are shared
What are the minimum ratios for CN 3, 4, 6 and 8?
rm/rx=rc/ra
What are the phases of silicates and their transformation temperatures?
At which point does deformation accur?
What happens if dry clay is put into contact with water?
The layers expand due to the polaric nature of water.
