High quality Random shapes of sic board introduction

Oxide Bonded Silicon Carbide, we can make different shapes, which is used for firing general chinaware and ceramic product (temperature below 1,450°C), is made by SiC bonded by Silicon Oxide (Si2O3), and technically called "Oxide Bonded Silicon Carbide".
This Random shapes of sic board has very high thermal conductivity (almost 10 times higher than mullite refractory) and high radiation rate of Long-wavelength infrared that bring very high heat efficiency toward products.

Random shapes of sic board can offer good heat stability, high thermal conductivity, and excellent corrosion resistance against chemicals, high abrasion resistance and high distortion resistance. It has been widely used in electronic ceramic, emery wheel and magnetic material.

Precaution to the Users

1.The storage spot of SiC refractory materials should be kept tried, away from mist and wet.

2.Do not pile the SiC refractory materials on the top of another, it is preferable to put them in a vertical order.

3.After the SiC refractory materials plate is sprayed with alumina solution, it should be laid dried around the kiln before use.

4. To get longer useage and avoid damnification, the SiC refractory materials should lay dried and put on the refractory plate.

5.After the products is glazed, the bottom of glazed product should be cleaned.

6.When building refractory plates, the refractory supporter should be aligned.

7.The distance between refractory plates should keep upon 14-20mm.

8. The design of sintering curve should meet the requirement of normal operation. Avoid heating or cooling in a short time.

9.When cooling takes place, it should be cooled gradually, avoiding exerting cold air to get a fast cooling.

10.When moving from the kiln, one should avoid carrying it at high temperature or hitting 

Advantages
