Abstract
A non-detonable shaped charge capable of becoming detonable upon activation. The shaped charge may be utilized for use with a perforating gun in oilfield applications. In this regard, during transport and other handling in advance of reaching the application site, the charge may be non-detonable. However, upon an intentionally directed activation, such as through heating, the shaped charge may be detonable.
