One thing that tetrazoles lack is a good oxygen balance.
What provides the means of keeping the oxygen balance?
The theoretical compound trinitrotriazine has an oxygen balance of zero.
Odrade used the pause to recompose her oxygen balance.
Oxygen balance is an expression that is used to indicate the degree to which an explosive can be oxidized.
RDX is also has a negative oxygen balance.
For this reason heptanitrocubane, the slightly less nitrated form, is believed to have marginally better performance despite having a worse oxygen balance.
Tetrazoles have a low oxygen balance, meaning that they don't have enough oxygen atoms in its structure.
One area in which oxygen balance can be applied is in the processing of mixtures of explosives.
One quality this explosive has, that PETN does not, is a positive oxygen balance.
"Through whatever mechanism has kept the oxygen balance stable for millennia," Haidar replied, pound-ing on her armrest.
After the silence had continued and when he had restored his own oxygen balance, he bent and checked the condition of the dark-haired boy.
"Paleoclimatology: the Oxygen Balance."
The addition of the carbon-containing methyl group in methylammonium nitrate imparts better explosive properties and helps create a more favorable oxygen balance.
In spite of the power drain, he dialed internal cool- ing as high as it would go; increased the oxygen balance sup- plied by his tanks.
Due to its bond strain and perfect oxygen balance, tetranitrotetrahedrane, an analogue of tetrahedrane with four nitro group substituents, has potential as a high-performance energetic material.
Blood flow, temperature, pressure and oxygen balance are monitored, as are a variety of chemical factors including acidity, potassium and the concentration of blood sugars.
It has a perfect oxygen balance, potentially making it a very powerful explosive, though calculations predict it would be fairly unstable and inferior to the related compound 3,6-dinitro-1,2,4,5-tetrazine.
Because sensitivity, brisance, and strength are properties resulting from a complex explosive chemical reaction, a simple relationship such as oxygen balance cannot be depended upon to yield universally consistent results.
Having a positive oxygen balance means that ETN possesses more than enough oxygen in its structure to fully oxidize all of its carbon and hydrogen upon detonation.
The sensitivity, strength, and brisance of an explosive are all somewhat dependent upon oxygen balance and tend to approach their maxima as oxygen balance approaches zero.
Oxygen balance is important for explosives, as it represents the percentage of available oxygen atoms in a molecule that can react with the other atoms (oxidation is a major energy source).
Although both RDX and TNT have a negative oxygen balance, the superheated aluminium component tends to contribute primarily by extending the expansion time of the explosive product gasses.
TNT-sensitized water gels were commercially successful, but the TNT led to problems with oxygen balance: namely elevated amounts of combustion by-products such as carbon monoxide and nitrogen-dioxide complexes.
