Helium-3: The top of the clean energy
Helium-3 has the following characteristics: Low radioactivity Helium-3 is a colorless, odorless, odorless, stable isotope of helium that is extremely low in radioactivity. This makes it a great advantage in many radiation-sensitive applications such as medicine, scientific research, and space exploration. Hyperfluidity Heliu...

How stable is silane?
Silane is poor in stability and has the following characteristics: 1. sensitive to air: easy spontaneous combustion: silane can spontaneous combustion when in contact with air. At a certain concentration, even at lower temperatures (such as -180 ° C), there will be a violent reaction and explosion with oxygen. When it burns, the fl...

The key principle of carbon dioxide filling weight
The weight of carbon dioxide depends mainly on the volume of the cylinder and the filling factor. In general, the carbon dioxide filling coefficient is about 0.6Kg/L, This means that the maximum filling capacity of a 10L cylinder is 6kg. However, in the actual filling process, it is necessary to avoid overfilling to prevent...

5N high purity nitrogen standard consistency analysis
The purity standard of high purity nitrogen is 99.999%, which is widely recognized in the international scope, and it is also clearly stipulated in the Chinese national standard GB/T 8999-2008. This means that high-purity nitrogen, whether produced at home or abroad, can be called 5N high-purity nitrogen as long as its purity reaches ...

Reactivity of Krypton with Fluorine Gas
Krypton, a noble gas found in trace amounts in the Earth’s atmosphere, is best known for its inert and non-reactive nature. However, when exposed to fluorine gas, a highly reactive halogen element, krypton exhibits a surprising reaction that defies its typical behaviour. In its natural state, krypton is an odourless, colourless...

Rare gases: Rising stars for bright electro-optical appli...
I. Introduction to Rare Gases Rare gases are gases found in very small amounts in nature, including helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn), to name but six elements. These rare gases are widely used because of their high stability, low chemical activity and very low boiling points. Among them, ...

Is 99.999% pure hydrogen chloride a gas or a liquid?
Hydrogen chloride (HCl) This is a compound of hydrogen and chlorine atoms. Under standard conditions (i.e. normal temperature and pressure), hydrogen chloride is in the gaseous state. When the temperature and pressure change, the state of HCl also changes. At low temperatures or high pressures, HCl can become liquid or solid. In sc...
