The use of rare gases

The uses of rare gases are: making neon lights, inflating, artificial air, laser technology and electric light sources.

1, making neon lights: Rare gases play an important role in making neon lights. Rare gases such as neon can be filled into the bulb, which makes the bulb have stronger light transmission ability, avoids light loss and can maintain brightness for a long time. Therefore, rare gases are widely used to make neon lights.

2. Inflating: Inflating is a common way to fill balloons, airships and other gases. By filling a certain amount of ammonia, the balloon or air boat can be kept in a stable and comfortable state.

3. Artificial air: It is used for divers to breathe, because in the high-pressure deep sea, the solubility of nitrogen in ordinary air is small, and it is easy to form bubbles in blood. When divers rise from the deep sea, their bodies gradually return to normal pressure, and nitrogen dissolved in the blood increases, forming bubbles, leading to air congestion. However, the solubility of helium in blood is low, which can be avoided by replacing air with helium.

4. Used in laser technology: Rare gas can be used in laser technology, because the high-energy laser beam generated by rare gas in laser has high precision and stability. Neon and argon in rare gases can produce stable laser beams under appropriate conditions, without interference and energy loss. This feature makes laser technology widely used in laser, optical instruments and other fields.

5. As an electric light source: Rare gases can produce unique colored light in electro-optic due to their spectral characteristics, such as purple light and green light. Therefore, rare gases are widely used in the field of lighting, especially in the manufacture of LED lamps.
