Creating a Fused Silica Glass Lung by Using Selective Laser-induced Etching Technology

November 3, 2023

Technical glass enables unique features that are interesting for a wide variety of high-precision applications. Glass is chemically inert, therefore it remains chemically stable in harsh environments. Moreover, technical glass e.g. fused silica is resistant to high temperatures and enables excellent optical transmission without any auto fluorescence from deep UV to mid IR.

These properties together with the mechanical specifications regarding hardness, Young’s modulus and high isotropy degree make glass an interesting choice for many medical, scientific, and industrial applications where high levels of precision and durability are required.

Sometimes classic machining technologies as grinding or cleaving can leave stress or sub-surfacedamage, however there is a new machining technology is able to overcome the aforementioned disadvantages. Read more [Source: ivam.de]

Glass and Ceramic Materials in Ultra High and Ultra Clean Vacuum

December 11, 2021

Glass and ceramics have functional advantages and disadvantages compared to metals due to their functional properties. Both materials are used in Ultra High Vacuum (UHV) and Ultra Clean Vacuum (UCV). Glass benefits from its low coefficient of thermal expansion (CTE), its inertness towards harsh chemical environments and low thermal and electric conductivity. A good example is the use of glass as an insulator for high voltage feedthroughs. Read more
