1/11/2014· When calcium is used as an additive in tin oxide, the calcium ions may occupy the substitutional sites in the SnO 2 matrix or get segregated at the grain boundaries as CaO phase. A considerably larger ionic radius of Ca 2+ (1.14 Å) compared to that of Sn 4+ (0.83 Å) suggests a nominal substitution of Ca 2+ ions in the SnO 2 matrix  .

Recovery/Recycling Methods for Metal Finishers | …
Chelating resins can hold certain transitional metal ions (such as Cu2+ or Fe3+) very tightly, but do not hold tightly lighter metals such as sodium, magnesium and calcium. Because of this characteristic, chelating resins can be used to recover low concentrations of valuable or toxic metals from solutions that contain a high level of unwanted background salts.
The Importance of d-block Transition Metals
The Importance of d-block Transition Metals By: Daniel Bates The d-block transition metals have great importance in our lives. They are building blocks for life and are found directly in the center of the periodic table. The d-block simply means that the elements’ d-orbitals are the last to get occupied according to the building-up principle.

Metalloid - Wikipedia
"Meta-metal" is sometimes used instead to refer to certain metals (Be, Zn, Cd, Hg, In, Tl, β-Sn, Pb) loed just to the left of the metalloids on standard periodic tables. These metals are mostly diamagnetic  and tend to have distorted crystalline structures, electrical conductivity values at the lower end of those of metals, and amphoteric (weakly basic) oxides.  "
Overview of Transparent Metal Mesh Electrode Technologies
Definitions & key parameters • ‘Transparent’: per the normal definition.However, typically the metal structures block light, but due to very low surface coverage and microscopic feature size they appear transparent to the observer. • ‘Mesh’: the microscopic patterns of the conductive metal or metallic
