Magnesium hydroxide has piqued my interest lately, particularly for its use as a fire retardant. This remarkable substance is eco-friendly and has a wide range of applications, such as in the manufacturing of fire-resistant cables and plastics. The way it works is pretty fascinating - upon heating, it decomposes into magnesium oxide and water, which in turn helps to suppress flames and prevent fire spread. I'm thrilled to learn about such an environmentally friendly solution that can help keep our homes and workplaces safer. It's truly amazing how a simple compound like magnesium hydroxide can make such a significant impact on fire prevention and safety.
