That's pretty much it. Crystalline oxides have a regular lattice structure, whereas amorphous have no regular lattice structure, or regularly ordered array of anions and cations. Glasses tend to be amorphous, while ceramics have a crystalline structure.darkelf said:Can anyone explain the difference between amorphous and crystalline oxides.
I've tried google but can't find anything useful. I'm guessing that crystalline oxides should have a crystalline structure and as such crystalline properties. Would that be right?
Amorphous oxides have a disordered atomic structure, while crystalline oxides have a regular and repeating atomic arrangement.
Amorphous oxides are often used as transparent coatings or protective layers, while crystalline oxides are commonly used in electronics and as catalysts.
Amorphous oxides tend to have higher electrical resistance and lower thermal conductivity, while crystalline oxides often have higher mechanical strength and are more chemically stable.
Amorphous oxides are typically formed through processes such as rapid cooling or chemical vapor deposition, while crystalline oxides are formed through controlled crystallization of a molten or solution-based precursor.
Examples of amorphous oxides include glass, amorphous silicon, and amorphous carbon. Crystalline oxides include common minerals such as quartz, feldspar, and calcite, as well as synthetic materials like silicon dioxide and aluminum oxide.
