Silicon carbide price quotation

Silisyum karbür ikiye ayrılır siyah silisyum karbür ve yeşil silisyum karbür. Affected by the economic cycle, the US dollar interest rate hike and the Russian-Ukrainian war, the price of black silicon carbide ranges from $1,400/ton to $2,700/ton, and the price of green silicon carbide is $2,000/ton to $3300/ton, different mesh, the price difference is relatively large.

By the continued influence of the market and the continued changes in supply and demand, the subsequent silicon carbide raw block prices continue to be bullish. Green silicon carbide sand fine number of serious shortage.

If there is demand in the near future, it is recommended to plan ahead!

Silicon carbide Introduction

Adamantine, silisyum karbür olarak da bilinir (sic) kuvars kumundan yapılmıştır, petrol koku (veya kömür kok), odun talaşı (salt is needed to produce green silicon carbide) ve dirençli fırınlarda yüksek sıcaklıklarda eritilen diğer hammaddeler. Silisyum karbür de doğada nadir bulunan bir mineral olarak bulunur., mozanit. Silicon carbide is also known as carbon silica. In the contemporary C, N, B and other non-oxide high-tech refractory raw materials, en yaygın olarak kullanılan silisyum karbür, en ekonomik olanı, altın çelik kum veya refrakter kum olarak adlandırılabilir. Şu anda, China’s industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, are hexagonal crystal, özgül ağırlığı 3.20 ~ 3.25, mikrosertliği 2840 ~ 3320kg/mm2.

Black Silicon carbide and Green Silicon carbide

Silisyum karbürün iki temel çeşidi vardır., siyah silisyum karbür ve yeşil silisyum karbür, both of which are α-SiC.

①Siyah silisyum karbür contains about 95% SiC, tokluğu yeşil silisyum karbürden daha yüksektir, çoğunlukla düşük çekme mukavemetli malzemeleri işlemek için kullanılır, cam gibi, seramik, taş, ısıya dayanıklı malzemeler, dökme demir ve demir dışı metaller, vb.

②Green silicon carbide contains about 97% or more sic, iyi kendini bileme, mostly used for processing cemented carbide, titanyum alaşımı ve optik cam, also used for honing cylinder liners and fine grinding high-speed steel tools.

Ek olarak, kübik silisyum karbür var, sarı-yeşil kristaller üretmek için özel bir işlemdir., aşındırıcıları rulman ultra ince işlemeye uygun hale getirmek için kullanılır, Ra32 ~ yüzey pürüzlülüğünü yapabilir 0.16 mikron için Ra0.04 ~ 0.02 bir seferde mikron.

Scope of application of silicon carbide

The application range of silicon carbide has four main application areas, namely: fonksiyonel seramikler, gelişmiş refrakter malzemeler, abrasives and metallurgical raw materials.
Silicon carbide crude material can be supplied in large quantities, which cannot be considered as high-tech products, while the application of nanoscale silicon carbide powder with extremely high technical content is unlikely to form economies of scale in a short time.

• (1) as aşındırıcılar, can be used to make abrasives, taşlama çarkları gibi, petrol taşları, taşlama kafaları, sand tiles, vb.
• (2) As metallurgical deoxidizer and high temperature resistant material.
• (3) High purity single crystal, can be used to manufacture semiconductors, manufacturing silicon carbide fiber.
