Boric acid at different temperatures state analysis
Published：2013/06/27 Views:3114
Boric acid induced heating 100 ℃, since constantly lose moisture, it first becomes borate, which has three variants, melting point of 176 ℃, 201 ℃ and 236 ℃. Boric acid dehydration to produce borate ended (as long as the temperature does not exceed 150 ℃). Then continue heating the water is off the net generation boron oxide. Boron oxide crystals melt at 450 ° C. Amorphous boron no fixed melting point, it begins to soften at 325 ℃, 500 ℃ all become liquid. Hazardous combustion products: boron oxide.
