and Answers


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.


Anisotropy - ANSWER✔✔-directionality of properties


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.


What do cations and anions prefer in terms of nearest neighbors? - ANSWER✔✔-Cations prefer to have

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)

coordination number? - ANSWER✔✔-The main relationship is 2(r_c + r_a) = sqrt(3)a.




Its coordination number is 8.


What is the main relationship between the unit cell and zinc blende structure (ZnS) and its coordination

number? - ANSWER✔✔-The main relationship is 4(r_c + r_a) = sqrt(3)a.

What is the equation for the volume of a sphere? - ANSWER✔✔-V=4/3 πr³


What are the examples of ceramics with rock salt structure (NaCl)? - ANSWER✔✔-Examples include

NaCl, MgO, MnS, LiF, and FeO.


What is the coordination number and structure of the CsCl structure? - ANSWER✔✔-Coordination

number = 8, anions @ corners of a cube, single cation @ center.
