The Achilles’ heel of ceramics is?
Ceramics can be made cheaply because what are the most abondent elements in the earth’s crust?
oxygen, silicon and aluminum
Using cross polarizers allows us to show what at the tip of a crack?
How can we strengthen ceramics?
Eliminate the cracks, or stop them from growing
Match the mechanism with the process:
1. Close surface cracks
2. Eliminate surface cracks
3. Limit surface cracks motion
1. Implant large atoms in surface
2. Flame polish a glass to remelt the surface to heal cracks
3. Make crystals smaller
T/F - The high strength of Corning Ware® is due to the larger crystals.
T/F - In Vision Ware® the crystals are even smaller than those in Corning Ware®.
T/F - Divitrification eliminates transparency in materials
T/F - Divitrification makes the material smaller
