SiC 98% purity black silicon carbide

Black silicon carbide is quartz sand, petroleum coke in primary raw materials, smelting in the high temperature resistance furnace. Its hardness is between corundum and diamond; the mechanical strength is higher than fused alumina, brittle and sharp. It has a certain conductivity and thermal conductivity.

▼Applications
●The application in the non-ferrous metal smelting industry
Use black silicon carbide’s high temperature, strength, good thermal conductivity and impact resistance, for high-temperature indirect heating materials, such as distillation furnace trays, aluminum tanks, copper melting furnace linings, zinc furnace arc plate, thermocouple protection tubes.
●The application in the iron and steel industry
Use black silicon carbide’s corrosion-resistance, thermal shock resistance to abrasion and good thermal conductivity for increasing service life of large-scale blast furnace lining.
●The application in the metallurgical ore processing
Black silicon carbide with strong wear resistance, second only to the diamond hardness, is the ideal material for wear-resistant pipe, impeller, pump chamber, cyclone and ore bucket lined, also for the aviation runway. The wear resistance is 5-20 times of cast iron, rubber life.
●The application in the building materials ceramic and grinding wheel industry
Use its characters of thermal conductivity, heat radiation and high temperature strength to make sheet kiln. It can not only reduce the kiln capacity, but also improve furnace installed capacity and product quality and shorten the production cycle. It is also the ideal indirect materials of sintering ceramic glazed baked.
●The application in energy saving
Use its good thermal conductivity and thermal stability to make heat exchanger, saving 20% fuel consumption and 35% fuel and improving the productivity by 20-30%. In particular, mine processing plant with a discharge pipeline in place, the abrasion resistant material is 6-7 times more than common.

▼Payment:
1).Our first choice is T/T. For a large order 40% T/T in advance is earnest money, the rest to be paid in 7-10 days after getting B/L copy. For a small order,100% T/T in advance.
2).Second choice is L/C. We can accept irrevocable L/C at sight. For a large order 40%T/T, 60%L/C. We couldn’t accept L/C for a small order. The best way of payment we advise is T/T, because L/C is very complicated and a lot of extra fee to give the bank.
3).The others: West Union, Paypal.
