Alumina in refractories Flashcards
1
Q
What are the chemical and physical properties of alumina as an ionic compound
A
High melting and boiling points
Does not conduct electricity unless its molten
conducts thermal
2
Q
Why does alumina have a high melting point
A
Because it has many strong ionic bonds
3
Q
How well does alumina conduct thermal energy
A
Its thermal conductivity is about 8 times less than aluminum metal.
