[0002] Magnesium-based inorganic materials refer to inorganic materials with magnesium as the main component, including magnesium alloys, magnesium oxides and magnesium salts. Magnesium is chemically an alkaline earth metal with low density and good chemical stability, so it is widely used in many industrial and technological applications.

[0003] The role and purpose of magnesium-based inorganic materials vary depending on the properties and characteristics of the materials. In the aerospace field, magnesium alloys are widely used as structural materials. Due to their excellent strength and lightweight properties, they can effectively reduce the weight of aircraft and improve fuel efficiency and flight performance.

[0004] During the production of magnesium alloy parts for aircraft, they need to be tested for fire resistance and high temperature resistance. Workers will use high-temperature torches to perform high-temperature tests on the more fragile parts of the parts. However, manual inspections lack precise time control and flame temperature control, resulting in incomplete inspection results for the parts. Utility Model Content
