-“ZINC” IS GERMAN FOR “JAGGED”-

Metallic zinc crystals have a needle-like or dendritic appearance because of their hexagonal close-packed (HCP) crystal structure, which creates anisotropic (direction-dependent) growth rates.

The growth conditions, particularly the degree of supersaturation, further exaggerate this effect, leading to the rapid elongation of the crystals in certain directions

Anisotropic growth from a hexagonal crystal structure

Hexagonal close-packed structure: Zinc naturally forms in an HCP crystal lattice. This structure consists of stacked layers of atoms in a hexagonal pattern. Unlike cubic crystals, which have symmetrical growth in all directions, HCP structures are not isotropic.

Preferred growth direction: In zinc, the atoms in the basal (hexagonal) plane are more tightly bonded than those connecting adjacent basal planes. This results in faster crystal growth along the prismatic axes, or length of the hexagons, and slower growth perpendicular to these planes.

Resulting morphology: This anisotropic growth causes the crystal to extend rapidly in one direction while widening more slowly, which produces the characteristic needle or rod shape. [4, 5, 6, 7, 8]

Influence of supersaturation and concentration

High supersaturation favors nucleation: When metallic zinc is grown from a solution or vapor under high supersaturation, the conditions favor the rapid nucleation of many small crystals. These crystals then grow quickly, but not uniformly.

Diffusion-limited growth: As the crystals grow, the zinc ions are consumed more quickly around the tips of the growing needles than along their flatter sides. This “diffusion-limited aggregation” (DLA) means that ions are more likely to attach to the most exposed parts of the crystal—the tips—than to the sides.

Positive feedback loop: This effect creates a positive feedback loop: the tips grow faster because they have a higher local concentration of zinc ions, which makes them even more prominent and increases their growth rate relative to the slower-growing sides. [9, 10, 11, 12, 13]

Environmental factors and dendritic growth

Electrodeposition: The needle-like growth is particularly pronounced during electrodeposition, a process used in applications like zinc batteries. A high electric field is concentrated at any microscopic protrusions on the electrode surface, attracting a higher flux of zinc ions and accelerating growth at these points.

Dendrite formation: If this growth goes unchecked, it can lead to the formation of tree-like, branched structures called dendrites. In zinc-ion batteries, these dendrites can eventually pierce the separator, causing short circuits.

Control of morphology: Researchers use different additives and modify electrodeposition parameters to control the growth and inhibit dendritic formation for practical applications. [2, 10, 14, 15, 16]

-“ZINCUM” IS THE LATIN WORD FOR “ZINC”-

“ZINCUM ACETICUM 2X”

-“HOMEOPATHIC DILUTION” VS “CHEMICAL CONCENTRATION”-

-ZINC ACETATE-

In zincum aceticum, the “2x” indicates a homeopathic dilution, meaning it has been diluted to a 1/100 concentration through a process of taking one part of the substance and adding it to nine parts of an inert solution, then repeating this step twice.

It signifies the product’s homeopathic preparation, not a chemical concentration, where ‘x’ denotes serial dilutions. [1, 2]
How the 2x Dilution is Achieved [1, 2]

First Dilution (1x): One part of the active ingredient (zinc acetate) is mixed with nine parts of an inert solution. This creates a 1x dilution.
Second Dilution (2x): One part of the 1x diluted solution is then mixed with nine more parts of an inert solution, which results in the 2x dilution.

Significance of the “x” [1, 2]

The ‘x’ in homeopathy refers to dilutions made with the decimal system.
A “1x” dilution is a 1:10 dilution.
A “2x” dilution is therefore a 1:100 dilution.

Therefore, in zincum aceticum (which is zinc acetate), the “2x” denotes that it is a homeopathic preparation where the zinc acetate has undergone two serial dilutions, resulting in a very high dilution. [1, 2, 3]
