On the Polymorphism of Calcium Carbide
Zeitschrift für anorganische und allgemeine Chemie, 1959AbstractA brief review of the literature is given. It is demonstrated that a recent suggestion regarding the alleged existence of a fifth crystal modification of calcium carbide was based on an erroneous interpretation of an X‐ray pattern. Doubt is also expressed as to a suggested molar volume for cuprous acetylide.
