 Tin granule product details (1) Product advantages: SN block Sn ≥ 99.99%, Sn particle Sn ≥ 99.999%, specific gravity 7.3, low melting point, only 232 ℃, you put it into the coal ball furnace, it will melt into mercury like liquid. Tin is very soft. You can cut it with a knife. The chemical properties of tin are very stable, and it is not easy to be oxidized by oxygen at room temperature, so it often keeps silver shiny. Tin is non-toxic. It is often plated on the inner wall of the copper pot to prevent the formation of toxic copper green (basic copper carbonate) by copper and warm water. It is mainly used for making wine pot, teapot and other food tools. (2) Product application: mainly used for the preparation of family compound semiconductor (such as pbxsn1 xTe), high-purity alloy, ultra-low temperature cooling alloy, superconducting material (nb2sn), solder, dopant of compound semiconductor, ITO material and other basic materials. (3) Product specification: 1 ~ 2.5mm, 2 ~ 4mm, 4 ~ 6mm, etc. Packaging: vacuum packaging. (4) Chemical composition and physical index (as shown below) (5) Product executive standard: GB / T 13747.22-1992
