Abstract
The organic substances NPG (neopentylglycol) and TRIS (tris(hydroxymethyl)aminoethane) are known to show a non-faceted/non-faceted peritectic phase diagram. The present investigation compares direct observations of the organic peritectic alloy made in a Bridgman furnace and differential scanning calorimetry measurements with the reported phase diagram. Investigations of the long-term stability showed decomposition tendencies depending on concentration and applied temperatures. Nevertheless, a process window is suggested which can be used for directional solidification experiments under stable conditions.
