Product Description
Cordierite ceramic is a low expansion special ceramic with 2MgO·2Al₂O₃·5SiO₂ as the main component, with excellent thermal stability, low dielectric constant and good thermal shock resistance. Its thermal expansion coefficient is close to zero, and it can withstand drastic temperature changes without cracking. It is widely used in electronic substrates, catalytic carriers and high-temperature filters.
