Forming gas ashing
WebJan 10, 2024 · Precipitate vs Precipitant . The terminology can seem a bit confusing. Here's how it works: forming a solid from a solution is called precipitation.A chemical that causes a solid to form in a liquid solution is called a precipitant.The solid that is formed is called the precipitate.If the particle size of the insoluble compound is very small or there is … Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. It is sometimes called a "dissociated ammonia atmosphere" due to the reaction which generates it: 2 NH3 → 3 H2 + N2 It can also be manufactured by thermal cracking of ammonia, in an ammonia cracker or forming gas generator.
