Additionally, AlN is a common alternative to Beryllium Oxide (BeO) in the semiconductor industry as it is not a health hazard when machined. An Introduction to Beryllium Oxide Ceramics. The sintering temperature of these high-performance ceramics is generally 1800~1900 C. Secondly, a suitable protective atmosphere should be selected to prevent AlN . Shapal Hi M Soft is a machinable Aluminum Nitride/Boron Nitride composite material that can be machined into incredibly tight tolerances and complicated shapes while still providing excellentthermal conductivity. Aluminum Nitride easily oxidizes at the temperatures above 1300F (700C), therefore it is not used in high temperature applications. Aluminum nitride(AlN) has high thermal conductivity and electrical insulation, and can be used in various electrical equipment. Aluminium nitride is a high performance material particularly suited to demanding electrical applications. Normally, the aluminium nitride is exposed to oxidation. Due to the inherent toughness and hardness of the material, this can be a time consuming and costly process. Main components of Macor are silicon oxide SiO2 ca.46 % , magnesium oxide MgO and about 17% aluminum oxide Al2O3 about 16 % . Aluminum nitride is stable at high temperatures in inert atmospheres and melts at 2800 C. This shrinkage means that it is impossible to hold very tight tolerances when machining AlN pre-sintering. Chamber Windows Used in a variety of semiconductor processing equipment parts for its plasma- and heat-resistance. Pintejin makes Aluminum Nitride (AIN) into common forms and finely machined parts for a variety of precision electronics applications, especially the semiconductor industry, and we supply high-quality Aluminum Nitride ceramic parts for chip manufacturing. WhatsApp: +86 15817370387 AlN is a covalent bond compound, atomic crystal, diamond-like nitride, hexagonal system, wurtzite crystal structure, non-toxic, white or grey white,The chemical composition is AI 65.81%, N 34.19%, theoretical density 3.26g/cm3. Aluminum nitride, but it had little practical application for more than 100 years, when it was . We are happy to provide advice on materials, design, and application. Prices for semi-finished and made parts of MCI GmbH upon request. Aluminum nitride was first synthesized by F. Briegleb and A. Geuther in 1862. The actual values can vary according to the shape and size of the envisioned component. Aluminum nitride ceramics have been used in many fields due to their high thermal conductivity, high insulation strength, low dielectric constant and dielectric loss, and excellent resistance to plasma erosion.
