New Chemical Trick To Make Fertilizer That Won't Explode
Sandia National Laboratories chemical engineer Vicki Chavez with Kevin Fleming Sandia National LaboratoriesIt turns out another industry's trash is fertilizer's lifesaver. The same chemical that makes fertilizer so useful also makes it really cheap bomb fuel. Researchers at Sandia labs in Albuquerque wondered if they could render the explosive properties of fertilizer inert while still keeping the beneficial properties intact, and this week announced success in a test batch. Even better, they're sharing the innovation for free. The problem with improvised explosives is that they're cheap, made from otherwise-harmless everyday materials, and the directions to make them aren't too hard to find. This is true of pressure cooker bombs, a terror weapon so ubiquitous that its been used by everyone from anarchists to religious radicals on at least three continents, and it's especially true of fertilizer bombs. Ammonium nitrate is the culprit. The first recipe for ammonium nitrate is over 350 years...
