The xenon fluoride market has not been well developed. The development level of xenon difluoride is relatively high.
Xenon, whose chemical symbol is Xe, appears as a colorless and odorless gas at normal temperature and pressure. It is a rare gas and an inert gas. According to the “Xenon Fluoride Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” released by the Industrial Research Center, xenon The compounds are mainly oxides and fluorides. There are three types of xenon fluoride, namely xenon difluoride (XeF2), xenon tetrafluoride (XeF4), and xenon hexafluoride (XeF6). They can all be stored in nickel containers or nickel containers. alloy container. Overall, the downstream application market of xenon fluoride has not yet been well developed. In comparison, the market development of xenon difluoride is relatively high. Let’s look at it in detail below.
The three types of xenon fluoride are made from xenon gas and fluorine gas as raw materials, mixed according to a certain ratio, and reacted under certain temperature and pressure conditions. The amount of fluorine added can determine the proportion of the final product. Generally speaking, within a certain range, the lower the amount of fluorine added, the higher the output proportion of xenon difluoride, and the higher the amount of fluorine added, the higher the proportion of xenon hexafluoride output. big. For example: xenon gas and fluorine gas react in a reactor at a ratio of 1:5. The main product is xenon tetrafluoride, and the by-products are xenon difluoride and xenon hexafluoride. In addition, xenon fluoride can also be prepared by discharge, radiation, photochemical reaction and other methods.
Xenon difluoride appears as colorless crystals and easily sublimates at room temperature to form a colorless gas. Among the three types of xenon fluoride, it has the weakest chemical activity and does not react with silicon dioxide. It has oxidizing and fluorinating properties. Milder. Xenon difluoride has the highest melting point, easily decomposes when exposed to water, is easily reduced to xenon in an alkali solution, is easily soluble in anhydrous hydrofluoric acid, and can be used as an oxidant and fluorinating agent. Industry analysts said that xenon difluoride is highly safe and selective when used as a fluorinating agent, and can also be used in uranium- 235 separation, preparation of new materials, chemical vapor phase etching and cleaning of silicon surfaces, etc., chemical vapor phase etching has been widely used at this stage.
Xenon tetrafluoride is the first rare gas binary compound discovered. It is a colorless monoclinic crystal. It easily sublimates to form a colorless gas at room temperature. Its chemical activity, oxidizing property, fluorinating property, and melting point are all in the Xenon difluoride and xenon hexafluoride do not react with silica. Xenon tetrafluoride will react when it meets water. The hydrolysis products are xenon trioxide and xenon gas. There is a danger of combustion and explosion when in contact with some organic matter. It is slightly soluble in anhydrous hydrofluoric acid. Xenon tetrafluoride is mainly used as an oxidant and a fluorinating agent for organic compounds. It can also be used as a moderator in nuclear reactors.
Xenon hexafluoride is a colorless monoclinic crystal that sublimates easily at room temperature. The color of the gas is different from xenon difluoride and xenon tetrafluoride, which is yellow. Among the three types of xenon fluoride, xenon hexafluoride has the most active chemical properties, the strongest oxidizing and fluorinating properties, and can react with silicon dioxide. Xenon hexafluoride has the lowest melting point and can react with water. The hydrolysis products are xenon tetrafluoride oxide and xenon trioxide. Sulfur hexafluoride can be used as a strong oxidant and fluorinating agent. Due to its strong reactivity and high risk, it can be used as an excellent fluorinating agent through modification.
