⩥ The silicates Key words Answer: 1. positively charged cations
- compensate neative charges in SiO4
- ionically bond the Si O4
⩥ The 2 Silicates subdivision Answer: 1. simple silicates - isolated
tetrahedra
2. layered silicates - sharing 3 oxygen atoms in each tetrahedra
⩥ What are the 3 forms of Carbon? Answer: 1. Diamond
2. Graphite
3. Amorphous State (lack an ordered internal structure)
⩥ What are the 2 types of imperfections in ceramics Answer: 1.
Frenkel defect
2. Schottky Defect
⩥ What is a Frenkel defect? Answer: Vacancy and interstitial pair.
(cation)
, When a cation leaves its normal position and moves into an interstitial
site.
⩥ What is a Schottky defect? Answer: Vacancy and Vacancy pair.
removing on of a cation and anion from interior of crystal and placing
them on outside surface.
⩥ What is rc and ra Answer: - rc is the radius of cations.
- ra is the radius of anions
⩥ Compare the sizes of anions and cations Answer: Anions(+) are
much larger than cations(-).
⩥ What type of bonds do diamonds have? Answer: Sp3 Hybridization
so that it bonds to 4 other carbons (tetrahedral)
⩥ What type of bonds does graphite have? Answer: Sp2
Hybridization allows each carbon to bond to three other carbons
