你说的这个在什么状态下是这个情况，应该温度在零下40度以上，零上40度以下都应该是不变的
IN preceding researches we have shown that fluorine is liquefied at – 187° C., and that, at this low temperature, It acts neither upon crystallised silicon, amorphous carbon, boron nor mercury; that, in short, its chemical activity is diminished, but t

Fluorine is a chemical element that comes in gas form as very pale yellow, in liquid form as bright yellow. In the solid form known as alpha, it is opaque and beta is transparent. Its melting point is (−219.67 °C, −363.41 °F) and the boiling point at (−188.11 °C, −3...
Fluorine changes from a gas to a liquid at a temperature of -188.13°C (-306.5°F) and from a liquid to a solid at -219.61°C (-363.30°F). Fluorine has a strong and characteristic odor that can be detected in very small amounts, as low as 20 parts per billion. This property ...
PFA flasks are chosen as containers when the solution is corrosive and requires a long reaction or heated reflux. The main purpose (1) Reactor between liquid and solid or liquid; (2) Assemble the gas reaction generator (normal temperature, heating); (3) Distil...
Adding chemistry's most electronegative atom to porous polymer networks may lead to gas-specific filters capable of flexible ‘breathing’. The tunable activity of metal–organic frameworks towards specific guest molecules, such as drugs or pollutants, has led to a flurry of recent research reports....
These ‘foils’ or pressed structures with milled composites were intended as ignitor fibers to tailor burn rates of solid propellants [136]. The inclusion of a fluoropolymer as an oxidizer contributed efficiently to the overall gas generation and energetic output of the ignitor-propellant system as...
9). The P-type inclusions consist of one phase (gas or liquid) are 3 to 15 μm (Fig. 9F). The W-type inclusions have visible liquid and at room temperature, irregular to round shapes, with size of 4 to 25 μm in diameter and vapor phases content of 20% to 60%. The S-type ...
