    High-Strength Wear- and Acid-Resistant Sintered Silicon Carbide Ceramic Sheets

    Image of Product. Front orientation. Ceramic. High-Strength Wear- and Acid-Resistant Sintered Silicon Carbide Ceramic Sheets.
    Sintering creates strong inner bonds, making this version of silicon carbide more resistant to wear and chemicals than other forms of silicon carbide as well as most ceramics. Since sintering doubles silicon carbide’s strength, you can replace thick sheets with a thinner sheet of this material. Using a thinner sheet reduces your system’s weight, heat loss, and energy needs. Chemical- and mechanical-finishing stations can be tiled with these sheets.
    With a hardness second to diamond, this silicon carbide holds up to abrasive rubbing applications and won't dent from impact. But this hardness means it’s difficult to machine and needs to be worked with diamond-tipped tooling. It’s more brittle than other ceramics, so it loses its strength if it cracks.
    This material is not as porous as other forms of silicon carbide, so while it’s gastight, it’s not as good at dissipating heat. It dissipates heat well enough to handle extreme temperature swings, but not when they're rapid.

    High-Strength Wear- and Acid-Resistant Sintered Silicon Carbide Ceramic Rods

    Create bushings and other parts that will be exposed to abrasion, harsh chemicals, high heat, and rubbing with these rods. Sintering strengthens the bonds within silicon carbide, leaving it two times stronger than other versions of silicon carbide. This means you can replace thicker rods with thinner rods, reducing the weight, heat loss, and energy needs in your system.
    This silicon carbide is second only to diamond in terms of hardness, so it holds up to abrasive rubbing applications and won’t dent from impact. However, its extreme hardness means it should be worked with diamond-tipped tools. It’s difficult to machine otherwise. It’s also more brittle than other ceramics, so if it cracks, it will lose its strength.
    Low porosity means this version is gastight but not as good at dissipating heat as other forms of silicon carbide. As a result, it can handle extreme temperature swings, but not when they’re rapid. Since all forms of silicon carbide stand up to high temperatures as well as chemicals, this material is frequently found in chemical processing plants, kilns, and boilers.

    Acid-Resistant Silicon Carbide Ceramic Balls

    Image of Product. Front orientation. Ceramic. Acid-Resistant Silicon Carbide Ceramic Balls.
    Extremely hard with excellent corrosion resistance, this silicon carbide ceramic is often used for rubbing parts such as bearings and bushings in chemical-processing environments. This material’s hardness means it resists abrasion and wear, but also makes it more brittle than other ceramics. Don’t use it under heavy loads or at high speeds. Nearly chemically inert, it resists corrosion better than other ceramics when in contact with acids and other chemicals. Silicon carbide ceramic conducts heat well and doesn’t expand significantly from heat, so it won’t deform or crack from temperature swings. Rated for use at up to 2550° F, it’s good for use in furnaces and refractories.
