Product Description

Product Description

Silicon carbide products lines:

 

1. Reaction Sintered Silicon carbide (RBSIC)

 

2. Recrystallized Silicon Carbide ceramic (RSIC)

 

3. Nitride Bonded Silicon Carbide ceramic (NBSIC)

 

4. Sintered Silicon Carbide (SSiC)
 

Isopressed Silicon Carbide Protection Tubes Isopressed or carbon bonded silicon carbide protection tubes (SCI) are less porous (8%) than nitride bonded but not as dense as oxide bonded tubes. Isopressed silicon carbide tubes have a maximum service temperature of 2800°F or 1550°C. Composition - 78.2% Silicon Carbide (Black, course grained Alpha / Beta mix), 18.7% Silica, 2.1% Sodium Oxide, 1.43% Aluminum Oxide, .44% Iron Oxide. Note: Isopressed protection tubes are coated with a silicon carbide glaze to reduce open porosity and the reactive surface area of the protection tube. This glaze is used to help prolong the service life of the tube.

Detailed Photos

Is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. 

SiC tube properties:

a. high temperature strength
b. superior thermal shock resistance
c. excellent wear resistance
d. good fracture toughness
e. mechanical fatigue and creep resistance
f. Excellent non-wetting property with good oxidation resistance

 

 

Application:
It is widely used in the production of aluminum, copper and zinc , as the lining material of the molten pool and electrolytic bath(reduction bath).
