Packaging & Delivery

Silicon carbide is in the shape of six edge crystallization gravity 3.20-3.26. Mic

r

o-hardness 2840-3320kg/mm2, which is between corundum and corundum emery, mechanical strength is  higher than corundum so it can be used as abrasives and other industrial materials. Mohs hardness is 9.5 grade, only less harder than the hardness diamond ( 10 grade). it has good thermal conducti

v

ity. it is a semiconductor, it is also the oxidation resistance at high temperature.

Stability of SIC:

because of the chemical stability, high rate of thermal, conductivity low coefficient of thermal, expansion, good wear

resistance

, it also can be applied to high grade

refectory

materials except for abrasives which is heart shock, small volume light weight, high strength and better energy saving, low grade sic can be used as good  

deodorizer

, it can hel

p

speed up the steel making, ge

t

better control of the chemical, components to up. grade the quality of the steel, also it is massively applied to the processing of electronic cheating

element

sic rod.

Four areas of sic application: 

Functional ceramics, high grade pefractory, abrasives, metallurical raw materials: 

(1) As abrasives, it can be used as grinding wheel sharpening stone grinding head and the sand tile.

(2) As metallurgival deoxidizer and high temperature resistant material.
(3) High temperature applications: Ultraviolet detector, stuctural, materials, astronomical, disk break, the clutch, diesel particulate filter filament pyrometer, the ceramic membrane, cutting tools, heating element, nuclear fuel, jewelry, steel gear catalyst carrier and so on.
(4) hgih purity single crystal semiconouctor, circuit element, silicon carbide fibre.
