high-temperature oxidizing atmosphere and the maximum temperature can reach 1850 ℃. In 1947, a Swedish company produced the first molybdenum disilicide heating rod with continuous improvement, in the 1990s, the heating rod temperature increased to 1850 ℃ and named Kanthal Super 1900C heating element. China realized molybdenum disilicide heating elements industrial production in the 1980s. At present, the molybdenum disilicide heating element has became an important equipment used in heat treatment, casting, high-temperature sintering, and other industrial and laboratory. </p> <img src="pic/molybdenum-disilicide-heating-rod.jpg" align="right" title="molybdenum disilicide" alt="molybdenum disilicide" > <p align="justify">High temperature heating rods (MoSi<sub>2</sub> heating elements) is resistance heating element used in high temperatures field and it has many good properties. High temperature oxidation resistance, in high-temperature oxidizing atmosphere, its surface will generate dense quartz glass protective film to protect the heating rods matrix. Besides, this protective film has regenerative function and automatic removal surface impurities adhesion function. The resistivity of MoSi<sub>2</sub> heating rod will rapidly increase with temperature rise, so that the heating rod at low temperatures has large power and the furnace can heat rapidly. At high temperature the power becomes small to prevent material overheating. In addition, the operation time has little effect on resistivity, that is, not aging, so old and new elements can be mixed used. Molybdenum disilicide heating rod is commonly used in electric furnace, because of its low power consumption, fast heating, easy to maintain and stable product performance.</p> <p>MoSi<sub>2</sub> heating rods not only can be used in an oxidizing atmosphere, but also can be used in N<sub>2</sub>, H<sub>2</sub>, NH<sub>2</sub> and an inert gas, but the corresponding temperature is limited. MoSi<sub>2</sub> is prone to accelerated oxidation at 400 ~ 700 ℃, so it is not suited to use in this temperature range. In addition, its surface load can reach tens of W / cm2, which is much higher than the metal heating element, so it is possible to make furnace wall to reach 100W/m<sup>2</sup>, greatly improve the production rate. MoSi<sub>2</sub> heating rods can be made into U-shaped, W and L-shaped.</p> <p align="left">If you have got any interest in molybdenum metals, please feel free to contact us by email: <a href="mailto:sales@chinatungsten.com;sales@ctia.com.cn;sales@tungsten.com.cn;sales@xiamentungsten.com">sales@chinatungsten.com, sales@xiamentungsten.com</a> or by telephone:86 592 512 9696/86 592 512 9595. <p><span class="leftpath"592>Related Links: <a href="http://news.molybdenum.com.cn" target="_blank">Molybdenum News & Prices</a> </span> </div> </div> </div> </div>  <div id="link"> <table border="0" cellspacing="0" cellpadding="0"> <tr> <td class="ftdl" align="right" valign="top">Moly Information</td> <td class="ftdr"><a href="http://www.chinatungsten.com" target="_blank">Chinatungsten</a> | <a href="http://news.chinatungsten.com/en/" target="_blank">Molybdenum Price</a> | <a href="http://news.molybdenum.com.cn/en/" target="_blank">Molybdenum News</a>| <a href="http://picture.chinatungsten.com" target="_blank">Molybdenum Pictures</a></td> </tr> <tr> <td height="36" align="right" valign="top" class="ftdl">Chinatungsten Group</td> <td class="ftdr"><a href="http://www.tungsten.com.cn" target="_blank">Tungsten Metal</a> | <a href="http://www.tungsten-carbide.com.cn" target="_blank">Tungsten Carbide</a> | <a href="http://www.tungsten-powder.com" target="_blank">Tungsten Powder</a> | <a href="http://www.tungsten-alloy.com" target="_blank">Tungsten Heavy Alloy</a> |<a href="http://molybdenum-needle.com" target="_blank"> Molybdenum Needle</a> | <a href="http://molybdenum-wire.com" target="_blank">Molybdenum Wire</a> <br><a href="http://molybdenum-rod.com" target="_blank">Mo Rod</a> | <a href="http://titanium-zirconium-molybdenum.com" target="_blank">Titanium Zirconium Molybdenum</a>| <a href="http://molybdenum-electrode.com" target="_blank">Mo Electrodes</a> | <a href="http://molybdenum-crucible.com" target="_blank">Mo Crucible</a> | <a href="http://molybdenum-foil.com/index.html" target="_blank">Mo Foil</a> | <a href="http://www.tungsten-molybdenum-sapphire.com/chinese/index.htm" target="_blank">Molybdenum in Sapphire Growth Furnace</a> </td> </tr> </table> </div>  <div class="modal-footer"> <div class="footer1">Address: 3F, No.25 WH Rd., Xiamen Software Park Ⅱ, FJ 361008,China</div> <div class="footer1">Phone:+86-592-5129696,+86-592-5129595;Email:<a href="mailto:sales@chinatungsten.com;sales@ctia.com.cn;sales@tungsten.com.cn;sales@xiamentungsten.com">sales@chinatungsten.com</a> <br /> Certified by MIIT:<a href="http://www.chinatungsten.com/certificate.html">闽B2-20090025</a>　<a href="http://www.chinatungsten.com/chinatungsten-iso.html" rel="nofollow">ISO 9001:2015</a> <br /> Copyright©1997 - <span > <script type="text/javascript"> year = new Date(); update = year.getFullYear(); document.write(update); </script> </span> ChinaTungsten  <script type="text/javascript" src="https://js.users.51.la/21496211.js"></script><br /> </div> </div> </div> <script type="text/javascript" src="js/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="js/bootstrap.min.js"></script>  <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-49588296-1']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?
