Advantages of graphite hot zone<\/h2>\n

It\u00a0is assembled from various graphite components such as cylindrical, disc-shaped, and block-shaped ones,\u00a0exhibiting\u00a0outstanding overall performance advantages.<\/p>\n

E<\/b><\/strong>xcellent high-temperature thermal stability<\/b><\/strong><\/p>\n

It can operate stably in the ultra-high temperature range of 2200\u2103 – 2800\u2103 for a long time in vacuum or protected atmosphere conditions.<\/p>\n

 <\/p>\n

G<\/b><\/strong>ood thermal radiation reflection effect<\/b><\/strong><\/p>\n

It results\u00a0in good temperature uniformity inside the furnace.<\/p>\n

 <\/p>\n

\uc548\uc815\uc801<\/b><\/strong>\u00a0\ud654\ud559\uc801 \ud2b9\uc131<\/b><\/strong><\/p>\n

It is unlikely to react with molten materials such as silicon and silicon carbide.<\/p>\n

 <\/p>\n

E<\/b><\/strong>xcellent processing performance<\/b><\/strong><\/p>\n

You can precisely customize\u00a0various components according to the furnace structure.<\/p>\n

 <\/p>\n

O<\/b><\/strong>verall high-temperature strength is high<\/b><\/strong><\/p>\n

With the\u00a0small\u00a0high-temperature creep, it has a long\u00a0service life.<\/p>\n

 <\/p>\n

G<\/b><\/strong>ood thermal conductivity<\/b><\/strong><\/p>\n

Because of the balanced heat transfer, it\u00a0ensures\u00a0a stable temperature field inside the furnace cavity.<\/p>\n

 <\/p>\n

E<\/b><\/strong>\ub6f0\uc5b4\ub09c \uc804\uae30 \uc804\ub3c4\uc131<\/b><\/strong><\/p>\n

This enables it to be directly used as a resistance \ubc1c\uc5f4\uccb4<\/a>, which is suitable for the power heating system of high-temperature furnaces.<\/p>\n

\u00a0<\/b><\/strong><\/p>\n

Uses of graphite hot zone<\/h2>\n

Semiconductor field<\/h3>\n

Single crystal crystal growth<\/b><\/strong><\/p>\n

Because of the\u00a0low impurity content and controllable temperature gradient,\u00a0it can construct a high-temperature chamber. So it\u00a0provides\u00a0ideal conditions for crystal nucleation and slow growth, which reduces defect generation and ensuring the quality of semiconductor wafers.<\/p>\n

 <\/p>\n

New material field<\/h3>\n

Powder and ceramic sintering<\/b><\/strong><\/p>\n

You can use it for sintering\u00a0nitride aluminum, silicon carbide ceramics, and hard alloy in a high-temperature environment. With the uniform\u00a0internal temperature field, and clean\u00a0atmosphere environment, it makes the sintered ceramic workpieces have better consistency in density. And then significantly improving the mechanical properties of new material components.<\/p>\n

 <\/p>\n

Metallurgical processing field<\/h3>\n

Vacuum heat treatment and brazing<\/b><\/strong><\/p>\n

It\u00a0can prevent the surface of the workpiece from oxidizing and decarburizing<\/a>, which eliminates\u00a0the need for subsequent extensive grinding treatment. You can use it to complete vacuum quenching, annealing, and vacuum brazing treatments within the graphite heat field. It can simplify the processing procedures, and improve\u00a0the metal material’s microstructure.<\/p>\n

 <\/p>\n

Photovoltaic energy field<\/h3>\n

\ub2e4\uacb0\uc815 \uc2e4\ub9ac\ucf58 \uc789\uacf3 \uc8fc\uc870<\/b><\/strong><\/p>\n

You can use it to\u00a0control the temperature changes throughout the process of silicon material melting and directional solidification. With the stable thermal field conditions, it\u00a0can optimize the crystal grain structure of the silicon ingot.<\/p>\n

 <\/p>\n

Powder metallurgy industry<\/h3>\n

High-temperature sintering of alloys<\/b><\/strong><\/p>\n

Because of a\u00a0stable temperature rise and small temperature fluctuations, it ensures\u00a0the dimensional stability of large-scale components after sintering. And it makes the\u00a0small batch-to-batch variations, which is\u00a0suitable for large-scale mass production.<\/p>\n

 <\/p>\n

Special material preparation<\/h3>\n

Graphitization processing<\/b><\/strong><\/p>\n

It can achieve ultra-high-temperature treatment above 2500\u00b0C, which completes\u00a0the crystal lattice reconstruction of the material. So it\u00a0improves\u00a0the conductivity of lithium battery negative electrode materials,\u00a0meeting the performance requirements of battery materials.<\/p>","protected":false},"excerpt":{"rendered":"

Graphite heat zone is a type of thermal field that is constructed by means of structural layout and multi-layer insulation system to create a uniform and stable temperature gradient. It is mainly composed of high-purity isostatic pressing graphite as the main raw material, formed by combining and assembling various graphite accessories such as heaters, insulation tubes, crucibles, diversion tubes, and support bases. It has excellent high-temperature resistance, electrical and thermal conductivity, vacuum stability, and heat reflection performance. It performs noticeably well in high-temperature heat treatment equipment, suitable for high-temperature process production requirements under vacuum and inert atmospheres. You can widely use it in semiconductor silicon carbide crystal growth, photovoltaic silicon ingot casting, and etc.<\/p>","protected":false},"featured_media":8391,"template":"","meta":[],"product_brand":[],"product_cat":[38],"product_tag":[],"class_list":["post-8390","product","type-product","status-publish","has-post-thumbnail","product_cat-graphite-products","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"\nGraphite
