Boric acid is heated to 100 ℃, due to constantly lose water, become metaborate it first, it has three variants, melting point 176 ℃, 201 ℃ and 236 ℃ respectively. Boric acid dehydration to produce metaborate ended (as long as the temperature does not exceed 150 ℃). After further heating, the water is stripped to form boron oxide. Crystal boron oxide melt when 450 ° C. The amorphous boron oxide has no definite melting point, it begins to soften, in 325 ℃ 500 ℃ all become liquid. Boric acid is a stable crystal, usually preserved without chemical reaction. Recrystallization and agglomeration occur when temperature and humidity fluctuate. When storing, keep away from drastic environment and keep the packaging intact.
