| Properties | Magnesium hydride can react with water at room temperature to produce hydrogen. It can also be used as a catalyst, reducing agent, etc. Magnesium-based materials are medium-temperature hydrogen storage alloys, which are easy to store, have mild reaction conditions, and are environmentally friendly by-products. They are promising hydrogen storage materials. Compared with other metal hydrogen storage materials, magnesium-based hydrogen storage materials have the following advantages: high hydrogen storage capacity; rich resources and low price; magnesium-based hydrogen storage materials have a good hydrogen absorption and release platform, which improves the utilization rate of hydrogen; hydrides are more stable, and hydrogen release requires a higher temperature, and most hydrogen release temperatures are above 200°C. |
| Use | Provided is a magnesium hydride type hydrogen storage emulsion explosive comprising an emulsion matrix and a sensitizing material in its components, characterized in that the sensitizing material is magnesium hydride. |
