Premium Silicon Carbide Engineering

Silicon Carbide (SiC), also known as carborundum, is an exceptionally hard, synthetically manufactured compound of silicon and carbon. Its diamond-like structure yields unparalleled mechanical strength, wear tolerance, and extreme thermal resilience.

Micro Engineering supplies precision-finished Silicon Carbide components engineered to operate in the most hostile environments. From high-speed rotary pump seal faces to chemical spray nozzles, our SiC products offer maximum reliability and virtual immunity to corrosive media.

Perfect for abrasive slurry processing, acid transfer pumps, power generation boilers, and high-temp vacuum kiln furnaces.

Mechanical Properties

  • Mohs Hardness: 9.5 (Diamond is 10)
  • Density: 3.10 – 3.15 g/cm³
  • Max Temp: 1,400°C (SSiC)
  • Flexural Strength: 380 – 420 MPa
  • Purity Level: ≥ 99.0%

Features & Benefits

Engineered to outperform conventional ceramic and metallic seal options.

Extreme Hardness

Boasting 9.5 Mohs hardness. Delivers outstanding erosion resistance, ideal for pumping abrasive slurries containing sand, ash, or grit.

Excellent Thermal Conductivity

Rapid heat dissipation properties prevent localized overheating, protecting the seal face from thermal shock and micro-cracking.

Acid & Alkali Immunity

Chemically inert structure is unaffected by strong acids, caustic soda, organic solvents, or oxidizing environments across all pH levels.

Low Friction Coefficient

Smooth tribological run-in characteristics minimize power loss, reduce structural drag, and extend the operating life of motor spares.

Engineering & Performance Factors

Comparing the performance limits of SSiC and RBSiC grades.

Performance Parameters SSiC (Sintered SiC) RBSiC (Reaction Bonded)
Manufacturing Process Pressureless Sintering (1950°C+) Liquid Silicon Infiltration (1450°C)
Free Silicon Content 0% (Pure SiC structure) 10% – 15% (Silicon filler)
Max Operating Temperature 1,400°C (Oxidizing) / 1,650°C (Inert) 1,350°C (Inert) / 1,380°C (Oxidizing)
Chemical Resistance Outstanding (pH 0–14) Good (pH 4–10, free Si degrades)
Dimensional Tolerance Limit ±0.01 mm (precision ground) ±0.05 mm (minimum shrink rate)
Primary Applications High-speed mechanical seal faces, chemical pump bushes, high-pressure sleeves. Large-scale slurry nozzles, structural furnace components, heavy wear tiles.

Typical Applications

Silicon Carbide components play critical roles across multiple industries.

01

Mechanical Seal Faces

Providing leak-free sealing configurations in heavy-duty oil refinery pumps, paper mills, and industrial chemical process lines.

02

Slurry Pump Impellers & Sleeves

Minimizing wear caused by sand, tailings, and dense ores in mining pipelines and mineral washing plants.

03

FGD Spray Nozzles

Resisting thermal shock and high velocities inside flue gas desulfurization systems at coal power plants.

04

Thrust & Radial Bearings

Installed inside canned motor pumps and submersible borehole drills where conventional lubricants cannot be utilized.
