About 8% by weight of cathode ray tubes is strontium oxide, which has been the major use of strontium since 1970. [3] [4] Color televisions and other devices containing color cathode ray tubes sold in the United States are required by law to use strontium in the faceplate to block X-ray emission (these X-ray emitting TVs are no longer in production).
Most of the world's production of strontium used to be consumed in the production of cathode-ray tube (CRT) displays. The glass contained strontium and barium oxide to block X-rays. Consuming 75% of production, the primary use for strontium was in glass for colour television cathode-ray tubes, [56] where it prevented X-ray emission.
Distrontium ruthenate, also known as strontium ruthenate, is an oxide of strontium and ruthenium with the chemical formula Sr 2 RuO 4. It was the first reported perovskite superconductor that did not contain copper .
The energy source for each device was a rod of plutonium-238 providing a thermal power of approximately 1250 W. [23] This fuel capsule, containing 3.8 kilograms (8.4 lb) of plutonium-238 in oxide form (44,500 Ci or 1.65 PBq), was carried to the Moon in a separate fuel cask attached to the side of the Lunar Module. The fuel cask provided thermal ...
Strontium and barium have fewer applications than the lighter alkaline earth metals. Strontium carbonate is used in the manufacturing of red fireworks. [75] Pure strontium is used in the study of neurotransmitter release in neurons. [76] [77] Radioactive strontium-90 finds some use in RTGs, [78] [79] which utilize its decay heat.
All other strontium isotopes have half-lives shorter than 50 days, most under 100 minutes. Strontium-89 is an artificial radioisotope used in treatment of bone cancer; [ 5 ] this application utilizes its chemical similarity to calcium, which allows it to substitute calcium in bone structures.
Strontium peroxide is an inorganic compound with the formula Sr O 2 that exists in both anhydrous and octahydrate form, both of which are white solids. The anhydrous form adopts a structure similar to that of calcium carbide .
