Black carborundum, a form of silicon carbide, is prized for its exceptional hardness, thermal conductivity, and resistance to chemical corrosion. Its manufacturing involves a series of carefully controlled stages designed to ensure material consistency and performance for industrial applications such as abrasives, refractories, and semiconductors.
The process begins with the preparation of raw materials, primarily high-purity silica sand and carbon sources (such as petroleum coke or coal). These are weighed and mixed in precise ratios to achieve the desired chemical composition. The raw mix often undergoes pre-treatment steps like drying and grinding to ensure uniform particle size and moisture content, which are critical for subsequent reactions.
The core manufacturing stage is the synthesis of silicon carbide through the Acheson process or alternative methods like chemical vapor deposition (CVD) for higher purity grades. In the Acheson process, the raw mix is placed in an electric resistance furnace where it is heated to temperatures between 2,000°C and 2,500°C. This high-temperature reaction forms black carborundum crystals.
Key techniques here include:
- Temperature control: Precise furnace temperature regulation to optimize crystal size and phase purity.
- Atmosphere control: Maintaining an inert or reducing atmosphere to prevent oxidation.
- Cooling rate management: Controlled cooling to avoid structural defects and stress.
Post-synthesis, the raw silicon carbide blocks or powders are crushed, milled, and classified into specific grain sizes. Depending on the end-use, the material is then formed into various shapes—grits, powders, or bonded abrasives—using methods such as pressing, extrusion, or molding.
Finishing processes refine the physical properties and surface quality. This includes:
- Sieving and grading for uniform particle size distribution.
- Surface treatments like coating with resins or metals to improve bonding in abrasive tools.
- Heat treatments to relieve internal stresses or enhance toughness.
