Characteristics

High purity, uniform particle size; large surface area & high activity; excellent thermal stability & refractory insulation; nano‑grade exhibits size/surface effects; weakly alkaline, soluble in dilute acids.


Advantages

High purity with low impurities; customizable size & good dispersibility; high activity (iodine adsorption ≥65); eco‑friendly, low addition; wide application; free samples & technical support.

Applications

Direct‑method Magnesium Oxide finds extensive utilization in the industries specified below:

Refractories, ceramic substrates, electronic insulation, rubber activator, paint filler, flame retardant, antacid, food additive, silicon steel release agent, waste treatment, catalyst support.


Production Technology

Main processes: ammonia process, aerosol salt ablation, sol‑gel, homogeneous precipitation, thermal decomposition (magnesite/dolomite), brine method, liquid phase precipitation (brucite).


Theory

Ionic compound (Mg²⁺/O²⁻); basic oxide forming Mg(OH)₂ with water; surface defects provide strong adsorption; flame retardancy via heat absorption & insulating layer; high‑temperature resistance from high melting point and structural stability.
