style="font-size:16px"><strong>Ürün Uygulamaları:</strong></span></p> <p>Lantan metal hedefleri mükemmel dielektrik sabitlerine sahiptir, bu da onları ideal yüksek K geçitli dielektrik malzemeler haline getirir. Bu hedefler, 5 nm'nin altındaki işlemlerde transistörlerin geçit dielektrik sabitini arttırmak ve geçit kaçak akımını azaltmak için kullanılır.</p> <p> </p> <p><strong><span style="font-size:16px">Teknik Avantajlar:</span></strong></p> <p>1. Hammadde olarak yüksek saflıkta lantan metali kullanıldığında, ürünün mutlak saflığı 4N'ye kadar ulaşabilir. Önemli safsızlıkların kontrolü O ≤ 2000 ppm ve C ≤ 100 ppm olmak üzere sıkıdır.</p> <p>2. Ortalama tane boyutu 100 μm'den azdır.</p> <p>3. Standart dışı ebatların özelleştirilmiş üretimi desteklenmektedir.</p></div><div class="pnbar cl"><p>ÖNCEKİ : <a href="/news-detail/Aluminum-Scandium-Alloy">Nadir Toprak Alaşım Serisi – Alüminyum-Skandiyum Alaşımı (Al-Sc)</a></p><p>SONRAKİ : <a href="/news-detail/Yttrium-Target">Yüksek Saflıkta Nadir Toprak Metal ve Alaşımlı Hedefler Serisi - Yttrium Target（Y）</a></p></div></div></div><div class="show-list-6"><div class="wp1200"><h2>İlgili ürün kategorileri</h2><ul><li><a href="https://hnrem.com/products_list/Chinese-magnesium-rare-earth-alloy">Çin magnezyum nadir toprak alaşımı</a></li><li><a href="https://hnrem.com/products_list/terbium-and-dysprosium">terbiyum ve disprosiyum</a></li><li><a href="https://hnrem.com/products_list/scandium-aluminum-alloys">skandiyum alüminyum alaşımları</a></li><li><a href="https://hnrem.com/products_list/magnesium-rare-earth-master-alloy">magnezyum nadir toprak ana alaşımı</a></li><li><a href="https://hnrem.com/products_list/dysprosium-metal-hardness">disprosyum metal sertliği</a></li><li><a href="https://hnrem.com/products_list/yttrium-metal-facts">itriyum metali gerçekleri</a></li><li><a href="https://hnrem.com/products_list/yttrium-silicate-powder">itriyum silikat tozu</a></li><li><a href="https://hnrem.com/products_list/Calcium-magnesium-alloy-factory">Kalsiyum magnezyum alaşımı fabrikası</a></li><li><a href="https://hnrem.com/products_list/scandium-metals">skandiyum metalleri</a></li><li><a href="https://hnrem.com/products_list/Aluminum-scandium-lanthanum-alloy-factory">Alüminyum skandiyum lantan alaşımı fabrikası</a></li><li><a href="https://hnrem.com/products_list/Chinese-aluminum-scandium-master-alloys">Çin alüminyum skandiyum ana alaşımları</a></li><li><a href="https://hnrem.com/products_list/Chinese-yttrium-zirconia-powder">Çin itriyum zirkonya tozu</a></li></ul></div></div><div id="footer"><div class="wp"><div class="foot-left"><div class="foot-logo"><img src="/static/upload/logo/1704872448825766.png" alt="logo"></div><div class="foot-contact"><div><p><span style="font-size: 24px;"><strong>Hunan Rare Earth Co., Ltd.</strong></span></p><p>Adres: No. 18 Xiangtai Yolu, Liuyang Ekonomik ve Teknolojik Kalkınma Bölgesi, Changsha Şehri, Hunan Eyaleti, Çin.</p></div><div><p>Mobil / Whatsapp: <a href="https://api.whatsapp.com/send?phone=8615111328177" target="_blank">+86 15111328177</a></p><p>Tel: <a href="tel:8619397988799" target="_blank">+86 19397988799</a></p><p>Faks: +86 731 85661506</p><p>E-posta: <a href="/cdn-cgi/l/email-protection#e5868a8b91848691a58d8b978088cb868a88">iletiş<span class="__cf_email__" data-cfemail="89e0e4c9e1e7fbece4a7eae6e4">[email protected]</span></a></p></div></div></div><div class="foot-right"><h5>Bizi takip edin</h5><div class="share"><a href="https://www.facebook.com/profile.php?id=61568305870759" aria-label="facebook" rel="nofollow" target="_blank"><i class="qico qico-facebook"></i></a><a href="https://www.pinterest.com/hngcxt/" aria-label="pinterest" rel="nofollow" target="_blank"><i class="qico qico-pinterest"></i></a><a href="https://www.linkedin.com/company/105001164/admin/dashboard/" aria-label="linkedin" rel="nofollow" target="_blank"><i class="qico qico-linkedin"></i></a><a href="https://www.youtube.com/channel/UC6jEc2jn5rlkRkvx1_xYHow" aria-label="youtube" rel="nofollow" target="_blank"><i class="qico qico-youtube"></i></a></div></div></div><div class="foot-nav"><div class="wp"><ul><li><a href="/about-us">Hakkımızda</a></li><li><a href="/product">Ürünler</a></li><li><a href="/quality-control">Kalite Kontrol</a></li><li><a href="/news">Haberler</a></li><li><a href="/research-service">Araştırma ve Hizmet</a></li><li><a href="/contact-us">Bize Ulaşın</a></li><li><a href="https://blog.hnrem.com/" target="_blank">Blog</a></li><!-- <li><a href="sitemap.html">Sitemap</a></li> --></ul></div></div><script data-cfasync="false" src="/cdn-cgi/scripts/5c5dd728/cloudflare-static/email-decode.min.js"></script><script type="text/javascript" src="/static/site/cookie-policy/cookie-policy.js" defer=""></script><div class="copyright"><div class="wp"><p>Telif Hakkı © Hunan Rare Earth Co., Ltd.
