Effect of metal chloride on thermal decomposition of nitrocellulose

The effect of various metal chlorides, namely FeCl3, AlCl3, CuCl2, and ZnCl2, on the thermal decomposition of nitrocellulose (NC) was studied using a synchronous thermal analyzer (STA). An aqueous solution of 10 mass% metal chlorides was added to NC and was then compared with pure NC. The results re...
