What are ceramics? ......ANSWER........Ceramics are elements
composed of at least two elements, often more, with complex
crystal structures that range from purely ionic to totally covalent.
What influences the crystal structure of ceramics?
......ANSWER........The electrical charge of ions and the relative
sizes of the anion and cation.
Why must a ceramic molecule be neutral? ......ANSWER........The
net charge across the cation and anion must be 0, and the whole
ceramic molecule must be neutral.
,age 2 of 27
What do cations and anions prefer in terms of nearest
neighbors? ......ANSWER........Cations prefer to have as many
nearest neighbor anions as possible, and anions prefer to have
as many cations as possible.
What are the most common coordination numbers in ceramics?
......ANSWER........The most common coordination numbers in
ceramics are 4, 6, and 8
What happens when the ratio of the radii is greater than 1?
......ANSWER........The coordination number is 12.
What are the 3 types of ceramic crystal structures?
......ANSWER........AX, AmXp, and AmBnXp Type
What are the 3 subdivisions of AX- Type ceramic structure?
......ANSWER........1. Rock salt structure (NaCl)
, age 3 of 27
2. Cesium Chloride Structure (CsCl)
3. Zinc Blende Structutre (ZnS)
What is the main relationship between the unit cell and rock salt
structure (NaCl) and its coordination number?
......ANSWER........The main relationship is 2(r_c + r_a) = a.
Its coordination number is 6.
How many anions and cations do you have in a Rock Salt
Structure? ......ANSWER........4 anions and 4 cations.
What is the main relationship between the unit cell and cesium
chloride structure (CsCl)and its coordination number?
......ANSWER........The main relationship is 2(r_c + r_a) = sqrt(3)a.
