antimony 121 is a stable (non-radioactive) metal isotope of antimony, naturally occurring and produced by fission. It is used to make flame-proofing materials and alloyed with other metals to improve their strength and hardness. It is also used as a dopant in semiconductor materials. It is found naturally in many places, but has been contaminated by mining and dumping. This isotope is produced at American Elements in standard and custom forms to meet your specific needs.
American Elements is a leading producer of stable metallic isotopes for biological, biomedical and target materials applications. In addition to antimony 121, American Elements produces more than 250 other stable isotopes for use in biological labeling, target material identification and research.
