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.
2.Features of Sic Ceramic Sleeve:
1) Heat shock stablity
2) chemical corrosion-resistant
3) High temper-endure(up to 1650°
4) Wearing/corrosion/oxidation resistant
5) Highly performance of mechanical strength
6) Cleaning or etching the hardest sub-surfaces
7) Used for grinding, lapping, and wire saw cutting as well as
abrasive blasting

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.
