HT-silicon carbide/SIC crucibles for melting

Product Description

Features of silicon carbide crucible:

a)Excellent Thermal Shock Characteristics
b)Corrosion Resistance
c)As Cast Tight Dimensional Tolerances
d)High Creep Resistance
e)Superior Wear Resistance
f)Maximum Use Temperature to 1600 °C

g)High temperature tolerance, high thermal conductivity, low coefficient of thermal expansion, oxidation resistance, thermal shock resistance, long application life.

Benefits:
a)Superior Oxidation Resistance
b)Improved Performance
c)Lowered Cost Burden
d)Longer Life Between Replacement/Rebuilds
e)Allows Lower Weight
f)Very High Thermal Conductivity

1.Thermal stability: We make special design to assure the quality accordig to the instant temperature changing working condition.

2.Corrosion resistance: Precise design extends the ability of corrision resistance of the crucible.

3.Impulsion resistance: Duratight graphite crucible can stand very strong heat impulsion, so it can be freely used in any technic process.

4.Acid resistance: Impregnation of special stuff can improve the quality of the crucible and its outstand in the acid resistance. As a result, it can prolong the work life of the graphite crucible.

5.Fine thermal conductivity: High content of fixed carbon ensures the good thermal conductivity, shorten the dissolving time and lower the cost of the oil and other energy obviously.

6.Control of metallic pollution : Strict control of the contents assures that there is no pollution to the metal during dissolving.

7.Quality stability: High-pressure manufacturing method and quality control system can pledge the quality stability better.
