Mat E 273 Final - CeramicsA common material for abrasives and heating elements - ANS-Silicon Carbide
A ceramic with some Metallic nature (eg shiny). A very hard ceramic that is not brittle -
ANS-Tungsten Carbide
A lightweight but hard material that is commonly used for ballistics armor - ANS-Boron Carbide
a dark shiny ceramic exhibiting very low friction coefficient. Used for bearings - ANS-Silicone
Nitride
Used as a coating on cutting tools; it improves tool life. Golden color - ANS-Titanium Nitride
(TiN)
Primary component of modern glass - ANS-Silica
Commonly used as a thermal barrier coating for jet engine blades, when modified with a small
amount of yttrium oxide - ANS-Zirconia (ZrO2)
an oxide that is commonly used for radioactive thermal generators (RTG) - ANS-Plutonium
Oxide
The compound commonly used as artificial diamond for jewelry - ANS-Zirconia (ZrO2)
a silicate based compound that is commonly used as an abrasive particulate in water jet cutting
- ANS-Garnet
an oxide compound that features natural electrical polarization due to a slight distortion of the
crystal lattice from its ideal structure - ANS-Barium titanate
a ceramic compound that has a very similar crystal structure compared to germanium -
ANS-Gallium Phosphide
this ceramic has an impressively high flexural strength. this is useful because flexure implies
that one side of the specimen is in compression and the other is in tension...and we know that
tensile states tend to promote crack growth - ANS-Zirconia (ZrO2)
A semiconductor compound that is commonly used for optical applications - ANS-Gallium
Phosphide
