Aluminum hydroxide is one of the main raw materials for the production of aluminium fluoride by drying technique. The moisture content of aluminum hydroxide is 5-10%. However, the production process of dry aluminium fluoride requires that the moisture content of raw material aluminum hydroxide must be less than 0.1% after drying before it can be used in production.
Calcium - Periodic table

Can calcium metal reacts with sodium hydroxide? What …
No calcium metal can''t reacts with sodium hydroxide because sodium is more reactive than calcium which means sodium has higher tendency to lose electron than calcium that''s why calcium can''t displace sodium from its aqueous solution.
