How to choose electrical grade magnesium oxide powder

Medium-temperature magnesium oxide powder is a variant of MgO. Medium-temperature magnesium oxide powder suits environments requiring a balance between reactivity and high-temperature resistance, making it ideal for all significant industrial environments. Chinese magnesium oxide powder can provide long-lasting performance from 800°C to °C, ensuring the powder maintains a balance between reactivity and stability. It is suitable for applications where reactivity is not high or low.

One of the outstanding features of medium-temperature magnesium oxide powder is its excellent thermal conductivity and insulation. The balance between thermal conductivity and insulation allows medium-temperature magnesium oxide powders to be used when heat must be carefully managed &#; either by dispersion to prevent localized overheating or by controlling heat to maintain energy efficiency. This duality makes medium-temperature magnesium oxide powder a versatile material in the electronics and construction industries.

In addition, electrical-grade magnesium oxide powder also has the characteristics of economy and availability.

This feature balances performance and cost well, making it a widely used and economically viable option for many industrial applications.

Magnesium Oxide Relationship with Magnesium Hydroxide

It is very common to hear someone in the wastewater treatment industry refer to something called &#;MagOx&#; as an alkaline additive they use to control pH or low alkalinity conditions.  Often they are simply using this term as a nickname when talking about either Magnesium Hydroxide or Magnesium Oxide, which is the chemical precursor to Magnesium Hydroxide, but which has very different properties.  So, when looking to obtain an additive that will provide the most cost-effective pH control performance for your wastewater treatment application, it is important to understand the relationship between Magnesium Oxide and Magnesium Hydroxide, and how not all products are equal.

First of all, the chemistry of Magnesium Oxide (MgO) and Magnesium Hydroxide (Mg(OH)2) is based on the Magnesium di-cation (Mg2+).  Magnesium is an essential macronutrient and is the core element in chlorophyll &#; the stuff that makes plants green and drives photosynthesis.  While MgO and Mg(OH)2 are very similar, knowing the differences in the manufacturing processes for each will help to understand the physical and chemical differences &#; which is very important in the selection process of the chemical best suited for your application.

Magnesium Oxide (MgO) is typically obtained from the calcination (heating) of Magnesite ore (Magnesium Carbonate or MgCO3) in much the same way as Quicklime (CaO) is formed from Limestone (Calcium Carbonate or CaCO3).  By changing the temperature and speed of how fast the MgCO3 passes through the heat zone, one can control the structure, porosity, and reactivity of the resulting MgO particles.  You may ask why this matters?  The more porous the particulate structure, having more available surface area, the more reactive the MgO.  The ability to control structure and porosity can result in the development of a wide range of MgO products with diverse properties for numerous industrial applications.
