Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 180–250 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 180–250 μm and a purity level exceeding 99.5% is a coarse-grained, high-performance ceramic material engineered for extreme mechanical and thermal environments. Thanks to its exceptional hardness (9.5 Mohs), high thermal conductivity, and chemical inertness, this grade of SiC is well-suited for applications requiring durability, thermal shock resistance, and structural strength.

Free of toxic or radioactive elements, this powder is ideal for use in demanding industrial settings including high-temperature refractories, advanced ceramics, thermal barrier components, and abrasive systems. It maintains its stability under high stress and harsh chemical environments, contributing to both performance and longevity in end products.
