Temukan Berbagai Jenis Keramik Silikon Nitrida dan Keunggulan Industrinya

There are various types of keramik silikon nitrida, including sintered silicon nitride and hot-pressed silicon nitride. They vary in properties, applications, and how they resolve problems in your advanced engineering or other extreme temperature environments. This guide explores silicon nitride ceramic types, their properties, benefits, and how to select the right type for your application.

Tinjauan Umum Keramik Silikon Nitrida (Sebagai Material Keramik Canggih)

• Silikon nitrida adalah senyawa kimia (a white, high-melting-point solid comprising silicon and nitrogen elements), and is represented with the formula Si3N4.

• A Si3N4 ceramic offers your process exceptional thermal resistance, mechanical strength, and thermodynamic stability.

• Berbagai jenis teknologi canggih ini keramik are each tailored to a specific use, and are often lightweight, very hard, and non-corrosive.

5 Main Types Of Silicon Nitride Ceramics

Classification of these types of silicon nitride ceramics is based on how they are produced and their exemplary properties.

Keramik Silikon Nitrida Sinter (SSN)

• Keramik Silikon Nitrida Sinter adalah material yang dibuat dengan cara tanpa tekanan sintering fine powders in a nitrogen gas atmosphere (at high temperatures of around 1750°C). They are widely used in your applications due to their balance of cost and performance.

• SSN ceramics offer your product excellent mechanical strength, fracture toughness, and oxidation resistance. Their mechanical properties make them ideal for your industrial application in making automobile engines and bearings, or metal forming.

“Switching to SSN in our turbochargers helped us reduce failure rates by 55%…It has been flawless for over 18 months now, and helps us achieve materials with near-zero porosity.”

 — Dan J., Insinyur Senior di AutoSys Components

Hot-pressed Silicon Nitride Ceramics (HPSN)

• HPSN is made using uniaxial pressure during the sintering process. Magnesia is added to a fine Si3N4 powder, and then the powder is placed in a graphite die.

• HPSN is typically costly, but it offers your product superior density and mechanical properties. It’s therefore ideal for your applications that require extreme precision and thermal shock, such as semiconductor manufacturing.

“Pemotong penggilingan HPSN telah meningkatkan kecepatan dan efisiensi secara signifikan dalam pemrosesan selongsong kami.”

Reaction-bonded silicon Nitride Ceramics (RBSN)

• RBSN is made through a careful process involving nitriding a silicon dough or compact at approximately 1450°C. RBSN also shrinks very little during processing, making it suitable for near-net shape production. This makes this type of silicon nitride ceramics a fit for your use in termokopel tabung pelindung dan cincin isolasi.

“RBSN memberi kami solusi hemat biaya untuk pelindung termokopel kami tanpa mengurangi keandalan.”

— Carlos M., Lead at HeatWorks Ltd.. 

Silikon Nitrida Sinter Tekanan Gas (GPSN)

• GPSN is obtained at very high nitrogen pressures, inhibiting the pyrolysis of silicon nitride and promoting the growth of Si3N4 grains. This ensures your process yields high-toughness ceramics with a high density.

• Compared to SSN, GPSN offers your application improved creep resistance at elevated temperatures. GPSN is an ideal choice for your production of wear-resistant components, nozzles, and dies for mid-range prices.

Keramik Nitrida Silikon Terikat Reaksi Sinter (SRBSN)

• Sintered Reaction-Bonded Silicon Nitride Ceramics is based on RBSN, aimed at improving RBSN’s density and mechanical properties. SRBSN combines the shape-control benefits of RBSN with enhanced mechanical performance close to that of SSN.

Aplikasi Keramik Silikon Nitrida untuk Industri Anda

• Silicon nitride ceramics offer your application outstanding physical and chemical characteristics. These silicon nitride properties include thermal resistance, lightweight strength, and chemical inertness.

• Your ideal industry applications include automotive, aerospace, electronics, medical, and industrial.

• Silicon nitride is also perfect for your LED packaging due to its optical transparency and being highly compatible.

Benefits Your Process Gets From Using Silicon Nitride

• Apakah Anda seorang insinyur or designer, silicon nitride ceramic offers high strength, excellent thermal shock resistance, superior wear resistance, corrosion resistance, and electrical insulation.

• And if you’re working in high-performance environments, expect longer equipment life, better efficiency, resilience, sustainability, and lower maintenance costs.

• Silikon nitrida memecahkan masalah teknik, menawarkan solusi yang andal dan berkinerja tinggi untuk mengganti logam yang rusak akibat panas atau korosi. Ambil contoh bantalan SSN, yang mengurangi keausan, atau alat pemotong GPSN, yang mempertahankan ketajaman lebih lama.

“Beralih ke silikon nitrida di berbagai komponen memangkas waktu henti pemeliharaan kami hingga 44%.”
