What Is Quartz Wafer and What Are Its Properties?

Quartz 4”,(ST-Cut) is one of the products that form the raw material of chips. Quartz Wafer can be fabricated at different sizes, different thicknesses, one side or two sides polished. Quartz Wafer is formed as a result of a process where at first quartz monocrystals are generated through hydrothermal synthesis.

During this process high quality particles of quartz are positioned at the bottom of a vessel which is loaded with NaOH. Quartz starts to crystallize at around 400°C and between 1000 and 1500 bar pressure. This crystallization eventually creates monocrystals and may take even days. The generated quartz monocrystals are polished after being sliced into wafers and finally reveal Quartz 4”,(AT-Cut) Wafers.

Quartz 4”,(X-Cut) has high thermal conductivity, high anti-corrosion, feature of high working temperature and good optical transmittance. For all these reasons Quartz Wafer is appropriate for the production of optical lenses, photomasks, microwave filters, semiconductors and for optical fiber applications.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
