What is Silicon Nitride?
Silicon Nitride is a ceramic wear-protection product made from high-alumina ceramic (typically high-alumina where specified), used to protect equipment from abrasive and impact wear. High-alumina ceramic gives hardness and chemical stability that defeat abrasion. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What is Silicon Nitride used for?
They protect process equipment from wear in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make Silicon Nitride effective?
High-alumina ceramic gives hardness and chemical stability that defeat abrasion. These properties let Silicon Nitride outlast steel and rubber in abrasive service.
Why choose Silicon Nitride over steel or rubber alternatives?
Silicon Nitride beat unlined steel or rubber on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. Silicon Nitride hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify Silicon Nitride?
Tell FIRSTAR your equipment, material and wear mode; we specify grade, size and backing to match.
What maintenance do Silicon Nitride need?
Little maintenance is needed beyond periodic inspection; because they wear slowly, planned replacement during shutdowns is usually enough. FIRSTAR can advise an inspection schedule.
