Dimethyl ammonium citrate

L. Dimethyl ammonium citrate (DAC) solution is prepared by dissolving 192.6 g of citric acid in 1 L of warm water. The solution is cooled and brought to 2 L by adding 891 mL of aqueous dimethyl ammonium solution (33 percent). A 5- to 10-second application of DAC on a polished surface structurally etches alite strongly and belite slightly. An optional preparatory etch with water for five seconds will aid in the identification of aluminate. 

Calcium sulfide (CaS) is isometric but resembles ferrite. It commonly forms colorless spherical or dendritic crystals, Is strongly reflecting, and rapidly etches with dimethyl ammonium citrate. It has an RI of 2.137 and perfect cubic cleavage. Hardness Is 4 and density is 2.6 Mg/ml Wustite (FeO) is isometric, black and nearly opaque at an FeO content of 80 percent. Wustite is opaque (bottle green) with an n of 2.12 at 78 percent FeO, with the remainder MgO. Wustite reflects gray-white with a...
