Green SiC (Carborundum) is made from Silica sand and coke, and is extremely pure. Hexagonally shaped, it breaks into very sharp particles.   How does Green Silicon Carbide differ from Black Silicon Carbide?  Green SiC is harder than black, coming in at a 9.4 Mohs and 2600 on the Knoop scale. Green Silicon Carbide is also of a higher purity than Black Silicon Carbide.  Green is often the media of choice when it comes to wire sawing, sintering, the making of high tech ceramic tools and parts.   

UNLESS your application requires an extremely pure SiC, or a maximum hardness rating, then by default, Black SiC is preferred due to its more economic pricing, as well as availability.   Please note that due to the global freight situation, many shipments are being delayed coming into this country.  Please plan ahead by a few months.

Sizes Available:

  • Macro Grit Sizes: 14 grit—240 grit
  • Micro Grit Sizes: Micro: FEPA 320 grit - F1200 grits
  • From time to time we will have JIS spec material in finer size only in stock, please inquire
  • Looking for very fine SiC-G powders?  You might try our Green Silicon Carbide 0.5 micron Sintering Flour, or our Wire Saw Slicing Powders
  • If you have a specific D50 you are looking for, send us your specifications and we can check lot numbers to see what we have that will work for you.  Our Alpha phase powders are used in the making of shapes, tools, parts, and other high tech ceramic pieces. 

Green Silicon Carbide Specifications:

  • Thermal Conductivity: High (100 W/m-K) approximately
  • High strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3)
  • SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2700°C.
  • Gradation:  Coarse grade meet both ANSI & FEPA; Grade 220 and finer are FEPA graded
  • Incompatabilities: None
  • Melting Point:   Sublimes at 4892°F (2700°C) - it does not melt at normal pressures but instead dissociates at 2700°C.

Wholesale Shipping & Packaging Information:

  • Default Packaging:  Default packaging is in 50lb pails, or 300 lb fiber drums.
  • Tote Packaging:  We can also package this in 2,200 lb super sacks. (1 metric ton) 
  • Discount Pricing:  Please use our Quote Request form to obtain custom pricing on larger quantities, with freight. 
  • Loading Dock:  Generally, you need to have a commercial address with loading dock to receive orders over 200lbs.  If you do not, we can ship it to a local terminal and you pick it up yourself from the terminal.  We can also ship to a residential address, but this is very costly and not recommended.
  • Lead Time:  2-3 Business Days to date of shipping due to ISO Quality Control paperwork that we must complete prior to shipping.

Retail 25 lb Box Discounts:   Note that orders of 50lbs or more are generally shipped in a 5 gallon plastic pail or a 50lb box.   They will not be shipped in 25lb boxes because this would increase freight costs.  Discounts apply the more you order.
