Rock Tumbling (Lapidary) Value Pack includes 10 lbs of each of the following most commonly used grades:  60/90, 120/220, 500/600, as well as 10 lbs of White Fused F1200 Aluminum Oxide as the final polish. 

Common Other Uses for Black Silicon Carbide Grit & Powders:

  • Ceramic, metal lapping, and polishing applications
  • SiC Sandpaper, grinding wheels, cut off tools
  • Slicing of silicon carbide wafers
  • Rock and stone polishing and engraving
  • Slicing, lapping, and polishing glass and germanium wafers
  • Lapping of piston rings and gears
  • Grinding of nonferrous materials
  • Finishing tough and hard materials
  • Bonded abrasive tool applications
  • Glass etching and glass carving industries
  • Rock tumbling industries - Lapidary use, vibratory machines
  • Making concrete "sparkle" in the sunshine
  • Concrete additive: anti-slip grit to broadcast on concrete flooring, sidewalks, plazas, driveways.  The 16/36 blend is perfect as a non slip broadcasting media.   (**NOT recommended around children's play areas or swimming pools as it will cause abrasion-type injuries when (not if) children fall down)

Specifications of Silicon Carbide:

  • Thermal Conductivity: High (100 W/m-K) approximately.
  • High strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3).
  • Black Silicon Carbide contains some free silicon (Si) and carbon (C) and is not as pure as Green SiC.
  • Incompatabilities: None
  • Gradation:  Coarse grades meet both ANSI & FEPA; 220 and Finer grades are FEPA Graded, "P" shaped particles are also available.  The entire ANSI and FEPA gradations are available.  "P" shaped media cannot be ordered online, you will need to call or email us for pricing.
  • Macro Grit Sizes: 8 grit - 240 grit (ANSI); P12 - P220 (FEPA).  Micro Grit Sizes:  F280 grit - F1200 grit (FEPA); P240 - P3000 (FEPA)
  • Typical Packaging: 300lb Drums, 50lb bags, 25lb boxes
  • Odor: Odorless
  • Safety: Avoid breathing dust; wear protective gear
  • Purity: 99% approximate
  • Friability: Semi-Friable
  • Pricing Based Per: Pound
  • Structure: Monocrystalline
  • NMF Classification: Class 55
  • Fire & Explosion: Fines can cause explosion and smolder
  • Keep away from all sources of ignition
  • Color: Black
  • Hardness: Knoop 2480 - 2550 / Mohs 9.1
  • Instability: Stable
  • Hazardous? Not listed as hazardous; see other cautions
  • Disposal: According to Federal, State, Local regulations
  • Grain Shape: Blocky, sharp edged OR we can also sell you "P" material, which is angular, with sharp edges.  "P" shaped media cannot be ordered online, you will need to call or email us for pricing.
  • Type: Granular or powdery depending on grade
  •  Specific Gravity: 3.2 (SiC)
  • Bulk Density: ANSI B74.12-1988   normal bulk Density range is 1.45 - 1.55  (If you need a high density media, ask us.  We can see if we have a lot number that meets your criteria.
  • Manmade from silica sand and carbon
  • Oxidation:  SIC will not oxidize until it reaches a temperature of ~1200C.  If it was placed in a harsh environment, such as an acid fog then it might oxidize earlier.  You might see a slight color change when the material is wet vs dry.
