Product Description

---------------------------------------------------------INTRODUCTION----------------------------------------------------------------

Silicon carbide (Chemical formula -- SiC), also known as emery and carborundum (It is called Siliziumkarbid and Siliciumcarbid in German). It occurs in nature as an extremely rare of the mineral: Moissanite. Black silicon carbide is hard, sharp, and brittle.

Silicon Carbide was first prepared in the early 1800s and was in commercial production by 1892, as a powder for grinding and cutting, having a Mohs hardness of 9-10 (almost as hard as Diamond). The grain edges of Silicon carbide are sharp and have a heat transmission capacity. Silicon carbide grains can be bonded together by sintering to form very hard ceramic which used in refractories' production.

Silicon carbide can be used as a deoxidizer and high-temperature resistant material in smelting. Also, it can be used to produce refractories and abrasive tools as raw materials, such as ceramic kiln furniture, plate, beam, frame, burner nozzle, grinding wheel, sandpaper, oilstone, grinding head, etc.

--------------------------------------------------------------CHARACTER--------------------------------------------------------------

1, Lead to more crystallization, larger crystals, higher purity and fewer impurities, longer melting time.

 

2, The longer life and better hardness.

 

3, Washed by chemical and water, cleanliness is excellent.

 

4, With special treatment, our products have a character of higher purity, excellent toughness, and grinding effect.

---------------------------------------------------------------APPLICATION ---------------------------------------------------------------

 

The application of Silicon carbide:

 

1, Functional ceramics

Silicon carbide has the advantages of high-temperature resistance, lightweight, high strength, good absorbing performance, etc. It also has a wide temperature range (can be used from room temperature to 1000 ° C), small dosage, adjustable dielectric properties, and can effectively reduce infrared radiation.

2, Refractories

Silicon carbide has the characteristics of wear resistance and high-temperature resistance and is widely used as the basic material of refractories

3, Abrasives materials

As its super hard properties, it can be prepared into various grinding wheels, abrasive paper and various abrasives.

4, Metallurgical deoxidizer

It could also be used as a reducing agent and heating element in steelmaking
