thorium within the earth's crust is much greater ( ppm) than other radioactive elements, particularly uranium . this makes thorium an attractive candidate for lowering the cost of nuclear power sources in the future. thorium is typically isolated by converting a sample of monazite or thorite to thorium...
for excellent non-detectable camouflage coatings due to their inability to absorb infrared heat. types of coatings optical coatings several types of coatings impart particular properties to optical components such as windows, lenses, mirrors, and other glasses . metallic and dielectric optical coatings...
tantalum, making them salts of tantalic acid. these compounds, which include lutetium tantalate, lithium tantalate, and lead scandium tantalate, are crystalline solids which exhibit optical, piezoelectric, and pyroelectric properties that lend them to uses as functional ceramics used in electronic sensors...
to concentrate these elements with much greater ease than other types of rare earth minerals. this relative ease of processing is key to the value of these clays, as their percentage composition of rees is low compared to the rare earth minerals discussed above. deposits of these clays in southern china...
