高温製造プロセスに革命をもたらす炭化ケイ素粉末

Unleashing the Amazing Properties of Silicon Carbide (SiC).

Raw materials used for manufacturing SiC undergo stringent purification processes, and then ground into fine powders for further processing.

Black SiC is widely utilized for use in abrasive applications such as grinding wheels and cutting discs to provide high performance and longevity. Furthermore, it benefits both metallurgical and iron industries by acting as a deoxidizer and additive.

硬度

Silicon Carbide is known for its hardness, making it ideal for applications requiring durability. Furthermore, its strength and abrasion resistance enable long-term performance with reduced maintenance requirements compared to alternative materials.

Thermal conductivity is another outstanding feature that allows it to quickly dissipate heat for fast and effective results. Coupled with its high temperature tolerance and low coefficient of expansion, this feature helps minimize dimension changes when exposed to extreme temperatures while guaranteeing structural integrity in components.

Black silicon carbide comes in multiple abrasive grit sizes and is versatile enough for many different manufacturing processes, including polishing, grinding and shaping ceramics and glass materials used in kilns, furnaces and refractories – as well as metals like aluminium and titanium – in kilns, furnaces and refractories as well as precision lapping and polishing processes. Additionally, its manufacturing is used extensively as part of bond and coated abrasives; additionally it’s widely found throughout industry processes for precision lapping and polishing processes as part of precision lapping and polishing operations.

Resistance to High Temperatures

Due to its chemical stability and high refractory temperature, silicon carbide has long been used as an industrial material in manufacturing abrasives as well as high performance ceramics. Due to its strength at high temperatures and impressive electrical conductivity, silicon carbide also finds use as wafer tray supports and paddles in semiconductor furnaces – not to mention resistance heating elements and temperature variable resistors (thermistors).

Silicon carbide powder is produced through the energy-intensive Acheson process, in which silica sand and carbon sources are heated at high temperatures to cause them to chemically react and form crystalline silicon carbide crystals, either Green or Black SiC (with Black SiC generally having lower purity levels).

Chemical vapor deposition is another effective means for growing cubic SiC, and used by both manufacturers and the semiconductor industry alike. This technique produces high-grade single crystals of 6H-SiC which offer both exceptional refractoriness and chemical stability.

熱伝導率

Silicon Carbide (SiC) boasts exceptional thermal conductivity compared to metals, helping it retain strength, stability and chemical resistance even under high temperature conditions. Furthermore, SiC provides outstanding abrasion resistance against wear.

SiC manufacturing requires significant energy. The Acheson process typically used in its production is energy intensive. By mixing silica and coke before heating them to high temperatures for chemical reaction to produce silicon carbide crystals that can then be ground down into various shapes and sizes to meet industry requirements.

Green silicon carbide powder is widely utilized by the abrasive industry for cutting and grinding tools that must be hard yet tough, while its properties make it popular as an additive in high performance ceramics, adding strength, refractoriness, and wafer tray supports and paddles in semiconductor industry furnaces. Furthermore, its electrical conduction properties make it perfect for use as thermistors and varistors due to relatively clean grain boundaries in solid-phase sintered SiC which don’t deform easily at high temperatures.

Abrasion Resistance

Silicon Carbide (SiC), commonly referred to as carborundum, is an abrasive material commonly used for cutting and grinding hard materials. As an essential raw material in the production of refractory materials for furnaces, kilns, crucibles as well as bulletproof vest ceramic plates it serves as both an abrasive head grinding wheel.

High Mohs hardness rating 13 ensures it can withstand shock and vibration well, making it suitable for use in environments prone to abrasion and damage. Diamond and boron carbide remain superior materials when it comes to shock resistance, providing you with reliable service even under high-pressure environments where wear-and-tear is likely.

Black SiC is an ideal material for precise lapping and polishing applications, offering a range of grit sizes suitable for precision applications. Thanks to its high purity and tightly controlled particle size distribution, it delivers consistent finishes every time. When glued onto coated abrasive bases like sandpaper or cloth it becomes an effective sanding block, sheet or sponge.
