| Small amounts of various metals, notably antimony and silver, are added to tin-lead solders to increase their strength. |
| Within these belts, gold mineralization is associated with rare metals, base metals, uranium, antimony, and mercury. |
| This black powder, called kohl, is usually made from antimony ground to an extreme fineness. |
| Beneath the surface lie layers rich in arsenic, phosphorus, copper, lead, antimony, even gold. |
| The most important of these are antimony, phosphorus, tin, and arsenic, with manganese and silicon having a small effect. |
| Doping with elements such as fluorine or antimony enhances its electrical conductivity and in turn its infrared reflectance. |
