Ytterbium

Ytterbium is a rare earth element of the lanthanide series and is found in the minerals gadolinite, monazite, and xenotime. The element is sometimes associated with yttrium or other related elements and is used in certain steels. The 169Yb isotope has been used as a radiation source substitute for a portable X-ray machine when electricity was not available. It can also be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel. Some ytterbium alloys have rarely been used in dentistry. It is used as dopant in optical materials, usually in the form of ions in active laser media. Ytterbium metal increases its electrical resistivity when subjected to high stresses. This property is used in stress gauges to monitor ground deformations from earthquakes and explosions.

Yttrium

Yttrium is a transition metal chemically similar to the lanthanides and it has often been classified as a "rare earth element". It is almost always found combined with the lanthanides in rare earth minerals and is never found in nature as a free element. The most important use of yttrium is in making phosphors, such as the red ones used in television cathode ray tube displays and in LEDs. Other uses include the production of electrodes, electrolytes, electronic filters, lasers and superconductors, various medical applications, and as traces in various materials to enhance their properties. Yttrium has no known biological role, and exposure to yttrium compounds can cause lung disease in humans.

Zinc

Zinc is a metallic chemical element. It is the 24th most abundant element in the Earth's crust and has five stable isotopes. Corrosion-resistant zinc plating of steel is the major application for zinc. Other applications are in batteries and alloys, such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate as dietary supplements, zinc chloride in deodorants, zinc pyrithione in anti-dandruff shampoos, zinc sulfide in luminescent paints, and zinc methyl or zinc diethyl in the organic laboratory. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation. The semiconductor properties of zinc oxide make it useful in varistors and photocopying products.
