Product Advantages

• Superior High-Temperature Performance & Long-Term Durability: With a guaranteed purity of 99.9%, this magnesium oxide exhibits exceptional thermal stability and maintains its mechanical and chemical integrity even under prolonged exposure to extreme temperatures (melting point ~2800°C). This makes it an ideal candidate for high-stress applications such as furnace linings, high-temperature reactors, and aerospace components, where long service life is critical.
• Enhanced Material Properties via Fine Particle Size & High Surface Area: The finely controlled particle size (typically 1–5 µm) and correspondingly high specific surface area promote superior dispersion and intimate interfacial contact with binders, fillers, or matrix materials. This synergistic effect improves overall composite properties, including mechanical strength, thermal shock resistance, and densification behavior during sintering.
• Outstanding Electrical Insulation for Demanding Electronic Applications: This high-purity MgO offers exceptional dielectric strength and high volume resistivity, making it an excellent choice for insulating layers, substrates, and packaging materials in power electronics, semiconductors, and high-voltage devices where reliable electrical isolation is essential.
• Versatile Applicability Across Multiple Industries: Thanks to its high purity, chemical inertness, and tunable morphology, 99.9% MgO finds broad utility in diverse sectors—including electronics (as a dielectric or substrate), ceramics (as a sintering aid and grain-growth inhibitor), refractories (as a high-temperature lining material), and chemical processing (as a catalyst support or adsorbent). Its adaptability simplifies supply chain management and reduces the need for multiple specialized grades.
• Non-Toxic, Environmentally Friendly, and Safe Handling: This magnesium oxide is classified as non-toxic and poses no significant health or environmental hazards when handled in accordance with standard industrial practices. It does not release harmful volatiles during processing, and its use aligns with increasingly stringent environmental regulations, making it a sustainable choice for responsible manufacturers.
