Magnesium oxide substrate (MgO substrate) available at Techinstro is in the form of thin-film wafers and blocks. Magnesium occurs naturally in nature with a combination of oxygen that coats a thin film, restricting it from burning. It is an alkaline metal oxide of earth and is found abundantly in seawater, underground deposits of brine, and deep salt beds. However, a calcination process of magnesium carbonate or magnesium hydroxide can obtain magnesium oxide. We uѕе CMP method to develop high-quality ѕubѕtrаtе providing excellent ѕmооthnеѕѕ at the atomic level. We provide this product at an economical cost, which is helpful for all kinds of researchers.


• Magnesium oxide substrate is a non-reactive provides acts as a superconductor.
• It has good corrosion resistance and does not react with iron, carbon, nitrogen, and sodium hydroxide.
• It has low electrical conductivity and therefore acts as semiconductors.
• It has an excellent thermal conductivity with a boiling point around 3600°C and a melting point ranging to 2852°C.
• Magnesium oxide (Magnesia) is the world’s largest single crystal (mоnосrуѕtаllіnе) and is abundant on earth and universe.
• It is transparent to various rays such as infrared rays, ultraviolet rays, and others.


There are a variety of applications of MgO substrates. Mainly, it is useful in developing superconducting films that withstand extreme temperatures in communication and space observation. It helps diamond growth and magnetic films such as MRAM, TMR, and an anti-reflective coating for window glass. It is also essential in ferroelectric film development that is applicable in thermometers and thermoregulator. The researchers may use it to perform experiments on the crystallization of polymers to observe epitaxial effects. The frequent application includes plasma display panels (PDP).


• Researchers should follow safety measures to protect themselves from any hazards while handling the product. It is in the list of Hazardous Substances by OSHA and cited by ACGIH and NIOSH.
• It is hazardous if the researcher breathes it causing eye irritation, nose irritation, and metal fume fever. Therefore, use a protective mask while handling the product and not bringing it closer to the nose and eyes.
• If symptoms like fever and chills, metallic taste in the mouth, headache, cough, and chest tightness occur, immediately reach medical assistance. The symptoms might take some time to show.
• Overexposure to the product may lead to cancer, infertility, or damaged reproductive system, and many long-term ailing illnesses.
• Use gloves to protect hands and PPE kits while handling the product.
• Take care that the area has excellent ventilation.
• Use goggles and face shields together to protect the eyes, nose, and face from getting affected.
• To clean any surface contamination from the product, use vacuum cleaners, or use a wet cleaning method. Do not dry sweep the remains.
• To avoid any changes in the crystal, protect it from exposure to a moist environment for a more extended period.
