The material systems for ceramic components encompass various categories of advanced ceramics, including oxide ceramics, nitride ceramics, boride ceramics, and carbide ceramics.
Oxide Ceramics: Examples include aluminum oxide (Al₂O₃), zirconium oxide (ZrO₂), and yttrium oxide (Y₂O₃). Characterized by high hardness, corrosion resistance, and excellent electrical insulation properties, they are widely utilized in wear-resistant parts, electronic substrates, and bioceramics.
Nitride Ceramics: Examples include silicon nitride (Si₃N₄) and aluminum nitride (AlN). Possessing high thermal conductivity, superior mechanical strength, and excellent thermal shock resistance, they are suitable for applications in semiconductor equipment and high-temperature structural components.
Carbide Ceramics: Examples include silicon carbide (SiC) and boron carbide (B₄C). Renowned for their extreme hardness, high wear resistance, and exceptional neutron absorption capabilities, they are employed in ballistic armor, cutting tools, and components for the nuclear industry.
Boride Ceramics: Examples include titanium diboride (TiB₂) and zirconium diboride (ZrB₂). Featuring extremely high melting points and hardness, they are predominantly used in high-temperature components within the aerospace industry.
