| 应用领域 | Uses: Used in the control rods of some nuclear reactors、Natural isotopes include Gd-152 (radioactive)、the remaining six isotopes are stable and comprise 99.8% of naturally occurring gadolinium、Mineral sources are samarskite、gadolinite (ytterbite)、and xenotime、[Merck Index] Used in high-temperature alloys and in electronic components、[Britannica]、Metal Preparation and Pouring [Category: Foundry]、Mining [Category: Industry]、As little as 1% gadolinium has been found to improve the workability and resistance of iron、chromium、and related alloys to high temperature and oxidation.、It has been used in making gadolinium yttrium garnets、which have microwave applications.、Gadolinium has the highest thermal neutron capture cross-section of any known element... Natural gadolinium is a mixture of seven isotopes. Two of these、(155)Gd and (157)Gd、have excellent capture characteristics、but they are present naturally in low concentrations. As a result、gadolinium has a very fast burnout rate and has limited use as a nuclear control rod material.、Neutron shielding、...phosphor activator、catalyst、scavenger for oxygen in titanium production.、Methods of Manufacturing: (1) Reduction of the、gadolinium、fluoride with calcium、(2) electrolysis of the、chloride with sodium chloride or potassium chloride in an iron pot that serves as an anode and graphite cathode.、Formulations、Preparations: Ingots、lumps、turnings、powder up to 99.9+% pure.、General Manufacturing Information: Gadolinium: ACTIVE |
