Translucent Alumina Ceramics

Overview

The translucent alumina ceramics, which developed by NGK's unique technics in material & manufacturing, achieves good translucency and thermal durability altogether.

Properties

• Excellent translucency

  This material is made of highly purified (99.99%) aluminum oxide (Al₂O₃). This material is sintered into a high-density polycrystalline substantially without pores that inhibit transmission of light. Reduction of grain boundary phase material and optimization control of the crystal grain size, achieves excellent translucency, which helps high efficiency of lighting source.

• Higher durability

  This material has its superior durability against corrosion, abrasion, and thermal shock. And withstands even in corrosive environments with high temperatures over 1000°C.

• Wide flexibility of designs

  This material can be formed in a variety of shapes and is applicable to various end piece configurations.

• Excellent quality controll

  NGK's continuing history of supplying this material since the 1970s is genuine proof of our long experience in high-level quatity control.

New Applications

This material has high thermal conductivity, and greater flexibility in manufacture design. Applying to various design like heat-spreading substrates, along with a highly efficient manufacturing process that requires no additional machining means greater flexibility in manufacture design for the customer.
