CRYSTALLIZATION OF AMMONIUM ALUM (Technical Report)

Alums crystallize in one of three different crystal structures. These classes are called α-, β- and γ-alums. The first X-ray crystal structures of alums were reported in 1927 by James M. Cork and Lawrence Bragg, and were used to develop the phase retrieval technique isomorphous replacement. [22] Solubility [ edit] See more An alum is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO 4) 2·12 H 2O, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often … See more Aluminium-based alums are named by the monovalent cation. Unlike the other alkali metals, lithium does not form alums; a fact attributed to the small size of its ion. The most important … See more Aluminium-based alums have been used since antiquity, and are still important in many industrial processes. The most widely used alum is potassium alum. It has been used since … See more Alum found at archaeological sites The western desert of Egypt was a major source of alum substitutes in antiquity. These evaporites were mainly FeAl 2(SO 4) 4·22 H 2O, MgAl 2(SO 4) 4·22 H 2O, NaAl(SO 4) 2·6 H 2O, MgSO 4·7H 2O and Al 2(SO 4) 3·17 H … See more Some alums occur as minerals, the most important being alunite. The most important alums – potassium, sodium, and ammonium – are produced industrially. Typical recipes involve combining aluminium sulfate and the sulfate monovalent cation. … See more Aluminium-based alums have a number of common chemical properties. They are soluble in water, have a sweetish taste, react as acid by turning blue litmus to red, and See more Many trivalent metals are capable of forming alums. The general form of an alum is XY(SO 4) 2·n H 2O, where X is an alkali metal or ammonium, Y is a trivalent metal, and n often is 12.
