Uses: As a very hard substance, silicon carbide is widely used as an abrasive. 

It is used to make various materials such as sandpapers, grinding wheels, cutting tools, hard ceramics, automobile parts, refractory linings, high temperature bricks, heating elements, wear-resistant parts for pumps and rocket engines, and even jewelry. 

It is also an important material in the electronics industry and used for making light-emitting diodes (LEDs) and semiconductor devices.


1. Commercial Grades 

Commercial silicon carbide products for engineering applications are commonly produced in three forms, sintered silicon carbide (SSC), nitride bonded silicon carbide (NBSC) and reaction bonded silicon carbide (RBSC). However, there are also several other types such as clay bonded silicon carbide and SiAlON bonded silicon carbide. The former is usually used for refractory applications, and many variations exist, depending on the manufacturer.

Silicon Carbide are that it is a refractory material (high melting point), it has excellent thermal conductivity and low thermal expansion, consequently it displays good thermal shock resistance. In addition, the high hardness, corrosion resistance and stiffness lead to a wide range of applications where wear and corrosion resistance are primary performance requirements. Silicon carbide possesses interesting electrical properties due to its semiconductor characteristics, the resistance of different compositions varying by as much as seven orders of magnitude.


2. Abrasives 

Silicon Carbide is a ceramic material with an outstanding hardness, only surpassed by diamond, cubic boron nitride and boron carbide.


Due to its high abrasion resistance and relatively low cost, Silicon Carbide is used as a loose- or fixed-abrasive material in a wide variety of applications.

These hard and brittle abrasive grains which tend to break down under pressure make SiC item sharper, cut faster and produce finer scratch patterns on most surfaces.

Abrasive tools made out of Silicon Carbide are commonly used for grinding steel, cast iron, tungsten carbide, aluminum & non-ferrous metal, plastic & rubber.


3. Refractory 

Chemical inertness at high temperatures, high resistance to abrasion and to thermal shock make Silicon Carbide an attractive material for several refractory applications. Typical examples are kiln furniture, aluminium reduction cells, incinerators, bricks for blast furnaces and zinc furnaces, crucibles, monolithics, tap hole clays and runners for melting furnaces.


4. Wire Saw SiC

Slurry Wire Saws are today established as the most commonly used tool to slice wafers from ingots, for the Semiconductor industry and for the rapidly growing sector of Photo voltaic (solar) power. Wire Saws slice many types of hard or brittle materials, most predominantly Silicon, but also other materials such as Quartz, Germanium, Gallium Arsenide, Gallium Nitride, Indium Selenide, Lithium Niobate.


Through the use of precisely controlled SiC grits, our customers can achieve, according to their own needs, precise cut-rates while limiting Total Thickness Variation, Warp, Bow and Sub Surface Damage to the wafers.
