Zirconium offers a very low absorption cross-section of thermal neutrons together with high hardness, ductility and corrosion resistance. Nuclear technology is one of its main applications, where it is used as cladding for fuel rods in nuclear reactors \u2014 particularly water reactors. A typical nuclear-grade zirconium alloy is composed of over 95% zirconium, with less than 2% tin, niobium, iron, chromium and nickel added to improve mechanical properties and corrosion resistance.<\/p>\n<p>Zirconium-tin alloys (Zr-2 and Zr-4) and zirconium-niobium alloys (such as Zr-2.5Nb) are the two main families produced industrially. In zirconium-tin alloys, elements such as tin, iron, chromium and nickel improve material strength, corrosion resistance and the thermal conductivity of the protective corrosion film, while reducing the sensitivity of the surface to corrosion. Because reactor cladding operates in 300\u2013400\u00b0C high-temperature, high-pressure water and steam, zirconium alloys are valued for combining good corrosion resistance with low neutron absorption and strong compatibility with nuclear fuel.<\/p>\n<div class=\"so-callout\">\n<h4>Key Properties<\/h4>\n<ul>\n<li>Very low thermal neutron absorption cross-section<\/li>\n<li>High hardness, ductility, and corrosion resistance<\/li>\n<li>Strong resistance to chemical attack \u2014 unaffected by most acids and alkalis except hydrofluoric acid<\/li>\n<li>Stable, self-protecting oxide film on the surface<\/li>\n<\/ul><\/div>\n<h3>Applications<\/h3>\n<h4>Refractory &amp; Ceramic Use<\/h4>\n<p>Zircon is widely used in high-temperature applications. Being refractory, hard, and chemically resistant, it serves as an opacifier that gives ceramic materials a white, opaque appearance, and is used in moulds for molten metals where aggressive environments are involved.<\/p>\n<h4>Nuclear Applications<\/h4>\n<p>Cladding for nuclear reactor fuel consumes about 1% of global zirconium supply, mainly in the form of zircaloys, selected for their low neutron-capture cross-section and corrosion resistance under normal service conditions. One operating consideration is that zirconium alloys react with water to release hydrogen, a reaction that is slow below 100\u00b0C but accelerates rapidly above 900\u00b0C \u2014 a property factored into reactor cooling and fuel-assembly safety design.<\/p>\n<h4>Space &amp; Aeronautic Industries<\/h4>\n<p>Zirconium metal and ZrO2 are used in space vehicles where heat resistance is critical. High-temperature components such as combustors, blades and vanes in jet engines and stationary gas turbines are increasingly protected with thin ceramic layers, typically a mixture of zirconia and yttria.<\/p>\n<h4>Medical Uses<\/h4>\n<p>Zirconium-bearing compounds are used across biomedical applications, including dental implants and crowns, knee and hip replacements, middle-ear reconstruction, and other restorative and prosthetic devices. Zirconium&#8217;s ability to bind urea has also been used in sorbent-based dialysis systems for patients with chronic kidney disease.<\/p>\n<p>  <\/main><\/p>\n<\/div>\n<p><script>\njQuery(document).ready(function($){\n  $('#so-acc-main').on('click', '.so-acc-btn', function(){\n    var $btn = $(this);\n    var $sub = $btn.next('.so-sub1');\n    var isOpen = $btn.hasClass('soopen');\n    $('#so-acc-main').find('.so-acc-btn').removeClass('soopen');\n    $('#so-acc-main').find('.so-sub1').removeClass('soopen');\n    if(!isOpen){\n      $btn.addClass('soopen');\n      $sub.addClass('soopen');\n    }\n  });\n  $(document).on('click', '.so-acc-btn2', function(){\n    var $btn = $(this);\n    var $sub = $btn.next('.so-sub2');\n    $btn.toggleClass('soopen');\n    $sub.toggleClass('soopen');\n  });\n});\n<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Categories Pure Titanium &amp; Alloys &#9660; About Titanium Titanium Tube and Pipe Titanium Strip, Sheet &amp; Plate Titanium Bar and Rod Titanium Welded Wire and Wire Titanium Foil Titanium Forging Titanium Flange Titanium Pipe Fittings Titanium Casting Titanium Fastener Titanium Elliptical \/ Spherical Head Titanium Machining Parts Titanium Clad Plate Titanium Clad Copper Bar<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-7025","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7025","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/comments?post=7025"}],"version-history":[{"count":1,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7025\/revisions"}],"predecessor-version":[{"id":7026,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7025\/revisions\/7026"}],"wp:attachment":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/media?parent=7025"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
