特徴について

アルミニウム窒化物(AlN)は、その優れた熱伝導性により、ハイテク分野で非常に重要な高度なセラミック材料です。 

電気絶縁材。窒化アルミニウムにまたそれに電子のための理想的な選択をする高い機械強さおよび安定した化学特性があります 

そして産業応用。

1.優れた熱伝導性と電気絶縁性

窒化アルミニウムはそれを必要とする適用で非常に貴重にさせるよい電気絶縁材と非常に高い熱伝導性を結合します、 

電気的な絶縁を必要としながら、効率的に熱を放散する。

効率的な放熱ソリューション:
アルミニウム窒化物の高い熱伝導率は、理想的な熱放散材料となります。 

例えば、パワー半導体、高密度集積回路、高周波電子部品などの高性能電子デバイス。 

これらのアプリケーションでは、性能の低下や損傷を防ぐために、材料が迅速かつ効果的に熱を伝導できる必要があります。 

過熱する。

電気アプリケーション:
高い熱伝導率を維持しながら、窒化アルミニウムは優れた電気絶縁性を持っています。これは特に重要です。 

例えば電力変換装置や高電圧電気アプリケーションなどの絶縁部品にとって重要であり、材料を必要とする 

電気を通さずに熱を効果的に伝える。

2.シリコンと同等の熱膨張係数と優れたプラズマ耐性

窒化アルミニウムの熱膨張係数はシリコンに非常に近く、その特性とプラズマ耐性により、それを実現します。 

半導体製造において特に重要です。

半導体の製造業:
窒化アルミニウムの熱膨張係数がシリコンと一致するため、熱応力が引き起こされます。 

温度変化は半導体装置の基質か熱インターフェイス材料として使用されたとき最小にすることができます。これは重大にです 

半導体デバイスの信頼性と性能を向上させる。

プラズマ抵抗:
半導体の処理の間に、部品は頻繁に腐食するかもしれない粗いプラズマ環境に抗する必要があります 

ある弱い材料を傷つけて下さい。窒化アルミニウムの優秀な血しょう抵抗はそれが性能および構造安定性を維持することを可能にします 

これらの条件の下で。

アルミニウム窒化物のこれらの特徴は、現代のハイテク分野、特に高性能電子機器において特に重要な役割を果たしています。 

装置および半導体の製造業。その優秀な物理的特性はだけでなく、装置の性能を改善しますが、また拡張します 

従ってプロダクトの耐用年数は、さまざまなデマンドが高い産業適用の信頼できる物質的な解決を提供します。
