Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur , not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder.
The company started by producing borax and potash from Searles Lake, at Trona, California. During World War II it diversified to other chemicals. In 1948, the company was San Bernardino County's second-largest employer, with 1,600 of Trona's 5,000 residents on the payroll. [7]
It built a new ammonium perchlorate plant in an isolated area about 14 miles (23 km) outside of Cedar City, Utah with a substantial voluntary no-build buffer around it. Natural gas service to this WECCO facility is handled in a different manner (mostly above ground away from AP storage areas) than was the case at PEPCON. [ 6 ]
The fuel/catalyst mixture is 90% 600-mesh dark flake aluminium powder, combined with the catalyst that is a mixture of 5% 325-mesh titanium sponge and 5% 200-mesh zirconium hydride [1] (with another patent document [10] listing 5% zirconium hydroxide). The oxidizer is a mixture of 85% 200-mesh ammonium nitrate and 15% ammonium perchlorate. [1]
Ammonium perbromate is much less hygroscopic in comparison to ammonium perchlorate, and has been shown to increase in weight when maintained in an atmosphere with high humidity. [ 2 ] Ammonium perbromate begins to decompose at a temperature between 170 and 180 Celsius, and has been observed to explode on occasion.
More than 200 chemical plants nationwide will be required to reduce toxic emissions that are likely to cause cancer under a new rule issued Tuesday by the Environmental Protection Agency. The rule ...
Both tests were done on 200 micron AP, the "nominal" size usually shipped in bulk (smaller particle sizes are available, but somewhat special order and nothing in the 15 micron range that I know of). These both conclude that 200 micron AP should not be designated a Class 1 explosive, but should keep its Class 4 oxidizer designation.
