Magnesium Oxide MgO content knowledge

When it comes to Magnesium Oxide MgO, I believe everyone is familiar with it. Do you know the difference between ordinary Magnesium Oxide MgO and activated Magnesium Oxide MgO? What does the content mean? Let's take a look today.


Magnesium Oxide MgO activity is an important indicator

When the temperature is 700 °C, the maximum conversion rate reaches the maximum value, and the residence rate is related to the surface area of ​​magnesium oxide. In the range of 900-1000 ℃, with the increase of temperature, calcined basic magnesium carbonate produces Magnesium Oxide MgO with low activity.


The role of Magnesium Oxide MgO in life

We will see all kinds of colorful clothes on the street, which will make us feel pleasing to the eyes, all of which are due to Magnesium Oxide MgO. Magnesium oxide can not only make our clothes beautiful, but also make our life colorful. In the production process of magnesium oxide, a chemical raw material called magnesium oxide needs to be added, so what is the role of magnesium oxide in magnesium oxide?

A brief introduction to Zirconium Fluoride ZrF4

The basic feature of Zirconium Fluoride ZrF4 is its easy absorption of hydrogen, nitrogen and oxygen. Oxygen has a strong affinity for oxygen. When oxygen is dissolved at 1000 °C, its volume increases significantly, and a smooth oxide film is easily formed on the surface of the fault, and its morphology is similar to that of steel. Corrosion resistant, but soluble in hydrogen acid and aqua regia.
