Silicon carbide (SiC) is an extremely durable non-oxide ceramic with outstanding thermal, mechanical and electrical properties. While SiC does not occur naturally in nature except as an extremely rare mineral moissanite, mass production started in 1891 by Pennsylvania inventor Edward G. Acheson. Hard as steel with a Mohs scale rating of 9 and sitting just …
Silicon carbide abrasives are hard, sharp abrasives that work effectively on metal, stone and wood finishes. Popular use cases include coarse grade stock removal and rough sanding operations. POWERTEC’s premium black silicon carbide sanding belts feature a closed coat for optimal grain coverage, making them an excellent choice for use on harder materials. Microfractures occur …
Silicon Carbide (SiC), commonly referred to as carborundum, is an extremely hard and durable ceramic material with low thermal expansion rates and great acid/lye resistance. Asbestos occurs as yellow to green to bluish black iridescent crystals that, when inhaled, may produce sustained nodular fibrosing alveolitis similar to that caused by crocidolite asbestos. Density Silicon carbide …
Silicon carbide (SiC) is an extremely hard synthetic crystalline compound of silicon and carbon that has been produced commercially since the late 19th century as an industrial abrasive and now finds widespread application as a high-performance ceramic application material. Moissanite can be found naturally in very limited quantities as a mineral and can be mined …
Silicon Carbide (SiC) is a solid industrial mineral crystal with ceramic and semiconductor properties. It can be colored using various impurities like nitrogen and aluminium. Silicon carbide is an ideal material for high-resolution astronomical telescope mirrors. Furthermore, silicon carbide is also utilized in power diodes, power transistors, and high-power microwave devices. High-voltage applications Silicon carbide …
Silicon carbide (formerly Carborundum) has become increasingly important for use in power electronics applications, particularly with Schottky barrier diodes. SiC Schottky diodes consist of a metal-semiconductor junction where only electrons flow, rather than holes as in traditional PN junction diodes. These devices feature rapid recovery times that enable smaller magnetic and passive components to be …

Silicon Carbide (SiC) power modules offer revolutionary new solutions for power applications, offering greater system efficiency in terms of system size, weight and form factor. Their higher operating temperatures, faster switching frequencies and smaller magnetics reduce system costs significantly. Vincotech addresses this challenge with advanced die-attach technology to mitigate SiC’s mechanical properties that decrease its …
与氧化铝砂纸相比，碳化硅砂纸具有耐用而有效的磨料特性，随着时间的推移，砂粒退化程度极低，因此能对木工项目进行精细加工。为任务选择磨料取决于其要求和材料特性，其中包括性价比、多功能性和强大的切割能力--碳化硅砂纸的这些特性...
碳化硅通常被称为碳化硅，具有卓越的耐热性，在 1400 摄氏度的高温下仍能保持较高的机械强度。此外，碳化硅还具有极高的硬度、抗疲劳性和在侵蚀性环境中的化学稳定性，这些都是任何材料的卓越标志。1891 年，爱德华-艾奇逊（Edward Acheson）发现了一种黑色小颗粒，并首次人工合成了碳化硅。
相干公司（Coherent）宣布，日本电装（DENSO）和三菱电机（Mitsubishi Electric）将共同向其碳化硅基板业务投资 10 亿美元，成立一家提供 150 毫米和 200 毫米碳化硅基板以及外延片的子公司。碳化硅是一种极具吸引力的功率半导体材料，因为它可以在比...
