Purity: MgO should be of high purity, typically 99% or higher, with minimal impurities that could affect its electrical properties.
Particle size: Particle size distribution is critical as it affects packing density and therefore insulating properties. Consistent and appropriate particle size helps ensure uniform insulation properties.
Packing Density: This is important for the filling process in manufacturing heating elements. It affects how MgO accumulates around the heating coil and can affect heat transfer and insulation.
Chemical stability: MgO should not react with other materials under high temperatures or electrical stress.
Dielectric Strength: High quality electrical grade magnesium oxide should have a high dielectric strength to act as an effective insulator and resist electrical breakdown.
Moisture content: Moisture greatly affects the electrical properties of MgO and should therefore be as low as possible.
Thermal Conductivity: While MgO is used for its insulating properties, it should also have the ability to conduct heat away from the heating element to prevent overheating.

Volume Resistivity: This is a measure of MgO&#;s ability to resist electrical current. High resistivity is essential for good insulation.
Loss on ignition (LOI): This test involves heating a sample of MgO to high temperatures to determine the amount of volatile material released. Lower LOI values indicate higher quality.
Specific surface area: Determined by the BET method, surface area affects the reactivity of the material and, in some cases, its insulating properties.
Sequestration of heavy metal impacted soil and groundwater Remediation is a remedial technology that has been employed for many years around the world by highly specialized remediation engineers who understand the chemistry well and its application. High reactivity and high purity MgO is much more than a low cost chemical buffer for pH control.
Sequestration is a process where chemical reagents like Metals Treatment Solution (i.e. MTS®) are applied or injected into soil or groundwater, industrial waste or substrate to form a stable and insoluble precipitate resulting in reduced leachability of the target heavy metals.
Heavy metal sequestration chemically binds metal ions in the free liquids and immobilizes them within the soil / substrate thereby reducing their solubility through the chemical reaction. The physical characteristics of the sequestrated or &#;stabilized&#; contaminated material is not changed by this process with respect to geotechnical properties for redevelopment. It also does not interfere with biological systems or native biota if shallow enough to be in the root zone.
