Zinc borate has a refractive index similar to most polymer systems, which results in the retention of considerable translucence. This allows the use of lower pigment loading as compared to antimony oxide. Zinc borate has a specific gravity of and is considered to be low toxicity.

Saffil is a trade name for shortcut alumina fibers made by Unifrax, primarily used in insulation appliions up to 1600 °C. Saffil fibers are 96% aluminum oxide and 4% silica, and have a density of g/cm 3, tensile strength of GPa, and melting point of 2000 °C. Ceramic oxide fibers are shown in Table 11.

Ideally, for healthy and productive soil the concentration of zinc should be 1‑200 mg/kg. If the concentration of nickel in your soil is greater than 7400 mg/kg it would be a good idea to test the food grown in your soil and seek expert advice about whether you need to take special corrective action in the levels are high.

Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite .
