In the form of boric acid, price per boron contained. Min. 99% pure. 6: C: Carbon: 2.267: 200 (5.54 × 10 18 kg) 0.122: 0.28: 2018: EIA Coal [19] In the form of anthracite, price per carbon contained, assuming 90% carbon content. There is a wide variation of price of carbon depending on its form.
Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]
A pure, 1-carat diamond can easily fetch a price in the six digits per gram. Prices can vary dramatically based on color, cut and other factors. ... Californium 252. Cost: $27 million per gram.
[1] Transuranic elements are difficult and expensive to produce, and their prices increase rapidly with atomic number. As of 2008, the cost of weapons-grade plutonium was around $4,000/gram, [2] and californium exceeded $60,000,000/gram. [3] Einsteinium is the heaviest element that has been produced in macroscopic quantities. [4]
Californium-252 production diagram Californium-252 (Cf-252, 252 Cf) undergoes spontaneous fission with a branching ratio of 3.09% and is used in small neutron sources . Fission neutrons have an energy range of 0 to 13 MeV with a mean value of 2.3 MeV and a most probable value of 1 MeV.
U.S. manufacturing activity contracted further in December, with a measure of factory output dropping to the lowest level in more than 4-1/2 years amid worries that higher tariffs would raise ...
As of Oct. 26, 2023, the price of 1 gram of gold is $64.16, whereas a gold bar that weighs a kilogram would fetch $64,160.67. How much is a 1-pound gold bar worth?
Few compounds of californium have been made and studied. [1] The only californium ion that is stable in aqueous solutions is the californium(III) cation. [2] The other two oxidation states are IV (strong oxidizing agents) and II (strong reducing agents). [3]
