1.Introduction of Silicon Carbide:
Silicon carbide (SiC), also known as carborundum, is a compound ofsilicon and carbon with a chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light emitting diode and detector in early radios have been demonstrated around 1907, and nowadays SiC is widely used in high-temperature semiconductor electronics. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as "synthetic moissanite". Silicon carbide with high surface area can be produced from SiO2 contained in plant material.

Q1.What is the difference between Refractoriness and Working temperature ?
A1:Refractoriness:the refractory material withstands high temperature without melting and softening performance in the absence of load resistance.Usually working temperature is less than refractoriness about 350-400°C.
Q2.How are the products' quality?
A2:The products will be strictly inspected before shipment, so the quality could be guaranteed.
Q3:What is the Warranty for the fire brick?
A3:For all the brick,we have 1 years warranty.If any quality problems on our side occured in this period ,we will take on the shipping cost and replacement.
Q4.What is the service life of the bricks?
A4:The service life of different bricks is unlike.It also depends on your using condition and method.
Q5:Are you a manufacture or trader?
A5:To be honest we are a trader,but we have stable cooperation factories.And we can supply good pre-sale service, after-sales service.
Q6.Can we visit your company?
A6:Sure,welcome at any time,seeing is believing.
Q7. Do you provide samples?
A7:Yes, samples are available.
Q8. Do you accept OEM?
A8:Yes, we can do OEM.
Q9.What's the MOQ of trial order?
A9:No limit,We can offer the best suggestions and solutions according to your condition.
Q10.What are the payment terms?
A10:Usually T/T,but L/C,Western Union etc are available for us.
Q11. How long is delivery time?
A11:The delivery time will be determined according to the quantity of the order.
