Magnesium Wall Board Composition
Natural Materials
Magnesium wall board is made from natural minerals and safe fillers. The main part is magnesium oxide. This makes the board strong and stops fire. Other minerals are added to help it last longer. The table below shows what is in magnesium oxide board:
Mineral / Compound | Typical Presence in MgO Boards (%) | Role / Notes |
|---|---|---|
Magnesium Oxide (MgO) | Core mineral, main component of the board | |
Magnesium Chloride (MgCl) | Up to 25 | Used as a binder or additive |
Magnesium Sulfate (MgSO4) | Present in some boards | Alternative binder, improves moisture resistance |
Silica (SiO2) | 2 – 18 | Adds strength and durability |
Fly Ash | Up to 5 | Filler to enhance strength and flexibility |
Perlite | Sometimes included | Improves moisture resistance and lightness |
Fiberglass Mesh / Gauze | Around 1 | Reinforcement to prevent cracking |
These minerals help mgo boards stay strong and flexible. They also keep out water and fire. Magnesium boards use magnesite. Magnesite is found in the ground and in seawater. People mine magnesite from the surface. This is better for the earth than digging deep mines. There is a lot of magnesium, so making these boards does not use up resources.
Tip: Using natural mineral fillers in mgo boards means less need for fake materials and glue. This makes magnesium wall board better for the planet.
