Silicon carbide CAS#409-21-2

Basic Information

Silicon carbide

Silicon carbide is a hard, covalently bonded refractory material with high abrasion resistance and tolerance of thermal shock. It occurs in multiple crystal structures, including cubic and hexagonal forms. Typical uses involve refractory components and bonded ceramic systems exposed to demanding wear or corrosion conditions. Reaction-bonded and sintered variants differ in physical behavior, while bonding-system selection influences permeability and chemical resistance.

product description

High Hardness & Wear Resistance:Extremely hard material with excellent abrasion resistance.


Corrosion & Slag Resistance:Performs well against molten slag and harsh environments.


Thermal Shock Resistance:Withstands rapid temperature changes without cracking.


High Conductivity & Multiple Structures:Offers good electrical conductivity and various polytypes for versatile applications.


Products Description of Silicon carbide CAS#409-21-2

Silicon carbide, a hard covalent material, is made by carbothermal reduction of silica at >2200 °C in electric furnaces. It features outstanding abrasion, corrosion and thermal shock resistance, with moderate electrical conductivity and oxidation susceptibility. It exists in hundreds of polytypes, mainly cubic β-SiC and hexagonal/rhombohedral α-SiC.


Product Application of Silicon carbide CAS#409-21-2

Silicon carbide, a rare fully synthetic refractory mineral, has four main bonding systems: oxide, Si₂ON₂, Si₃N₄ and self-bonded. The first three are permeable and prone to bond-phase corrosion, while self-bonded SiC is impermeable with only surface corrosion. Produced by reaction bonding or sintering, self-bonded variants have similar chemical resistance but distinct physical properties.
