99.6% High-purity Polished Grade Alumina Ceramic Substrate

99.6% High-purity Polished Grade Alumina Ceramic Substrate The 99.6% high-purity polished grade alumina ceramic substrate is an outstanding example in the field of advanced materials. It has numerous remarkable properties that make it indispensable in a wide variety of industries.   Containing 99.6% alumina (Al₂O₃), its purity is the foundation of its superiority. With extremely low impurity levels, it guarantees unparalleled stability and performance. This high purity directly leads to excellent electrical insulation properties, as its volume resistivity exceeds 10¹⁴ Ω·cm. It acts as a reliable barrier against electrical leakage, protecting the integrity of the electronic circuits in which it is applied, whether in power electronics, telecommunications, or consumer electronics. In terms of mechanical properties, it demonstrates remarkable strength and hardness. With a flexural strength ranging from 300 to 400 MPa, it can withstand significant mechanical str…
