Silicon Nitride


Silicon Nitride is produced industrially in a variety of phases. JohnsonFoils provides only the hardest, Beta-phase silicon nitride for paper industry applications. Silicon nitride ceramic is comprised of densely packed SiN rods, formed during the sintering process. This structure provides the geometry to generate the very smooth and dense surfaces that perform well on a paper machine. Silicon Nitride is a hard ceramic material with good wear resistance, but its major benefits are its fracture toughness, thermal shock resistance, and gentleness to fabrics. Silicon Nitride exhibits less brittleness and chipping tendency than most other ceramic materials.
