Silicon nitride and silicon carbide both have extremely high hardness and are among the best ceramic materials. They are often included in the same material selection list in high-end equipment, semiconductors, aerospace and other fields, but they differ significantly in performance focus and actual user experience. 1. Differences in physical properties Silicon nitride ceramics exhibit

Silicon Carbide (SiC) is widely used in EV power electronics, onboard chargers, DC-DC converters, and advanced automotive systems due to its high thermal stability, electrical insulation, and mechanical strength.However, not all SiC components meet automotive-grade reliability requirements. This checklist provides a complete and practical guide for engineers when selecting SiC components for automotive applications. Performance

Threaded features are very common in ceramic components. In advanced ceramics such as alumina, zirconia, Macor, Shapal-M, and aluminum nitride, thread sizes typically range from M1.2 to M8, and in some cases even larger. However, due to the brittle nature of ceramics, achieving Go-gauge pass and No-Go-gauge stop tolerances requires a different approach compared to

Engineering ceramics have become essential in industries such as semiconductor manufacturing, aerospace, medical devices, photonics, instrumentation, vacuum systems, and high-temperature applications. Each material—from Macor machinable glass ceramic to alumina, zirconia, aluminum nitride, silicon carbide, and silicon nitride—offers unique performance advantages. Selecting the right ceramic is critical for ensuring reliability, longevity, and manufacturing efficiency. Material-by-Material Breakdown

When engineering teams evaluate materials for high-pressure plunger pumps, metering pumps, hydraulic pumps, and precision fluid-delivery systems, zirconia ceramic (ZrO₂) consistently stands out as the preferred choice. Its exceptional wear resistance and chemical stability make it an indispensable material—superior to metals and other types of ceramics. Exceptional Fracture Toughness — The Core Reason Zirconia Suits

The semiconductor industry has always been the most widely used application of ceramics. Especially with the continuous upgrading of semiconductor equipment and technology, equipment manufacturers need high-performance and highly reliable materials for demanding processes such as deposition, etching, and photolithography. Alumina ceramics, due to their excellent thermal stability, insulation, and cost, help semiconductor equipment operate

Bending strength generally refers to the ability of a material to resist fracture under bending loads. Although both materials possess excellent properties, their bending performance differs due to variations in purity and sintering processes. Today, we will test aluminum nitride ceramics and alumina ceramics using a tensile testing machine, based on a commonly used 40

Thermal management is undoubtedly a crucial factor in today’s semiconductor, power module, and photonics systems industries. Whether using silicon, silicon carbide, or gallium nitride, the pursuit is for higher operational efficiency, switching speeds, and integration density. However, a common question remains: are current metal heat dissipation solutions still sufficient? After all, engineering ceramics, once considered

Having worked in the precision ceramics industry for a while, you’ll notice a pattern: what truly causes projects to fail is often not insufficient machining precision, but rather choosing the wrong materials from the outset. Many machining difficulties, unnecessary rework, and various anomalies during the testing phase, ultimately stem from a mismatch between material selection

First of all, it’s important to clarify that while alumina (Al₂O₃) contains aluminum, the aluminum does not exist in its metallic form. Therefore, alumina does not exhibit the electrical conductivity or chemical reactivity associated with metallic aluminum. This means it will not introduce metal contamination in applications such as semiconductors, aerospace, or medical device components.Below,
