Engineers and buyers in fields such as precision optics, semiconductors, and laser systems often require materials with extremely low thermal expansion coefficients for their equipment components. Low-expansion glass can minimize thermal deformation and maintain dimensional stability. Today, I’ll compare the five most commonly used low-expansion materials—Zerodur, ULE, ClearCeram (glass-ceramic), BF33 (Borofloat 33), and Fused Silica—to

Porous ceramic chucks are a type of vacuum chuck that uses micron/submicron interconnected channels to achieve uniform negative pressure adsorption. Compared to traditional grooved or perforated metal chucks, porous ceramics can provide uniform adsorption across the entire surface without localized depressions, greatly reducing the deformation and localized stress caused by thin wafers/wafers being “sucked into

In the semiconductor industry, Aluminum Nitride (AlN) and Silicon Carbide (SiC) have long been widely used due to their unique properties. This article compares AlN and SiC based on their characteristics and applications in the semiconductor field, helping you select the most suitable material. 1.Thermal Conductivity Semiconductor devices generate significant heat during operation, requiring high

Definition of Fused Quartz Fused Quartz / Fused Silica is an amorphous glass obtained by melting and rapidly cooling high-purity silicon dioxide. It features an extremely low coefficient of thermal expansion, excellent optical transmission (covering UV–visible–infrared ranges), high thermal resistance, and strong chemical corrosion resistance. These properties make it a key material in demanding applications

When working with advanced ceramics, the choice of manufacturing method can determine whether a part meets its performance requirements—or fails in service. Two common methods are ceramic machining and laser cutting. While both are widely used in industrial applications, they differ greatly in precision, surface quality, cost, and suitability for complex designs. This guide compares

Learn about material selection, machining processes, quality control, and supplier recommendations to find the best solution for your industrial projects. Custom Ceramic Parts (also known as prototypes) are precision components manufactured according to customer drawings. They are made from materials such as aluminum oxide, aluminum nitride, silicon carbide, Macor, and more, using cutting, grinding, polishing,

Recently, we custom-machined a batch of Zerodur glass cavity components for a scientific research institute specializing in precision inertial navigation systems. These cavities are used in the core assembly of laser gyroscopes. Zerodur is widely recognized as a key material in high-stability optical systems due to its ultra-low coefficient of thermal expansion and outstanding optical

Silicon carbide (SIC), one of the preferred materials in semiconductor manufacturing, has become a key part of the load-bearing and positioning components in semiconductor manufacturing equipment due to its high hardness, low thermal expansion, ultra-high rigidity and excellent chemical inertness, such as (carrier tray plate, wafer chuck, needle chuck, ring chuck, slot chuck, ceramic needle

In modern manufacturing, the continuous advancement of technology has driven rising demands for high-performance materials. Hard and brittle materials—such as various advanced ceramics and optical glass—are experiencing surging demand in sectors like aerospace, semiconductors, optical instrumentation, automation, and petrochemicals. Prototype manufacturing and rapid delivery have become mainstream trends within the industry. Optical glass materials (such

Although both glass ceramics and advanced ceramics are inorganic non-metallic materials, they are essentially two different materials. Advanced ceramics are derived from sintered powders, and their microstructure is uneven and inherently porous, which limits their ultimate mechanical and thermal properties. In contrast, glass ceramics are complex engineering materials. In the field of superhard materials and
