- Q: Are graphite crucibles suitable for melting composite propellants?
- Composite propellants are generally unsuitable for melting in graphite crucibles. Composite propellants are composed of oxidizers, fuels, and binders, which can be highly reactive and corrosive. Although graphite is known for its high melting point and resistance to high temperatures, it can react with certain components of composite propellants. When exposed to certain oxidizers like ammonium perchlorate, which is commonly found in composite propellants, graphite crucibles can undergo chemical reactions and erosion. This can result in contamination of the propellant and impact its performance. Additionally, the binders used in composite propellants can also react with graphite, causing the crucible to degrade and potentially fail. To melt composite propellants, it is advisable to use crucibles made from materials specifically designed for this purpose, such as ceramic or refractory metal crucibles. These materials have superior resistance to the corrosive nature of composite propellants and can withstand the high temperatures involved in the melting process.
