Can recrystallized magnesium oxide be dissolved by 1:1 hydrochloric acid? What is the most fundamental difference between it and lightly calcined magnesium oxide? Thank you, hero
I’m not very familiar with building materials, but since it’s magnesium oxide, it can certainly react with hydrochloric acid. I also searched the Internet for the difference between remelting and slight melting; I’m not sure if that will satisfy you. The so-called light-burned and heavily-burned magnesia differ mainly in terms of the sintering temperature; when the sintering temperature is below 1200 degrees, the resulting magnesium oxide is considered light-burned magnesium oxide, whereas when the sintering temperature exceeds 1200 degrees, the resulting magnesium oxide is known as heavily-burned magnesium.
Try using 20%–25% hydrochloric acid under pressure to raise the system temperature to around 140°C. The brother upstairs has a slight misunderstanding; of course—thermodynamics problems, definitely possible ； No — it’s a kinetic issue; the reaction doesn’t occur or happens so slowly it’s frustrating.
Is there any difference in the activity between lightly calcined magnesium oxide and heavily calcined magnesium oxide? Or is it the purity that differs?
