amorphous ceramic structure
Reasons why polymers are capable of forming amorphous structures?
Why polymers most likely to form structure amorphous below, metal or ceramic? What conditions favor the formation of amorphous structures?
Manufacture of amorphous metals is usually very difficult. High efficiency motors are composed of amorphous iron cores, but the amorphous iron is a beast to do. What They Do liquid iron is in the jet of liquid nitrogen cooling to millions of degrees per second. He is the only way to freeze faster than crystallized. Polymers However, large molecules with long, it takes much more time are rearranged into crystals, making it fairly easy to obtain amorphous. However, does depend strongly on the polymer structure, and some are almost impossible to amorphous to crystalline difficult around. Ceramics, I'm not sure. The Glass is certainly amorphous.
Which of the following are true statements ?
a) Amorphous solids have very regular cystalline structures wherein units cells can be easily defined.
b) Glass, ceramics, and cement are all examples of amorphous solids.
c) Materials containing Si-O bonds are generally resistant to compresive forces, but not to those that cause them to stretch.
d) An important process in the production of class is annealing, where the glass is cooled slowly as it passes from the viscous liquid state to the solid state. This process tends to keep the bonding forces in a more even array, thereby increasing the strength of the glass.
A) True
B) False
C) my different but i think your true
D) Mine says the quickly rather then slowly and it false so guess your true.
my answer was just A but my C and D are different so I think yours is ACD
sry if this is to late but i do my quiz late at night
