High Energy Mechanical Milling- Parameters for Optimizing Milling Efficiency

Posted by Chia-yu Chen on

Milling is a method to reduce solid particles to micron size level. It can also be used for mixing, blending and mechanical synthesis. Planetary ball mill is the most commonly used equipment for milling, but it is not easy to reduce particle size to nano size level by planetary ball mill. Various factors can affect milling performance, and it requires optimization. Typically, wet grinding performance can be better than dry grinding. The main factors affecting milling efficiency and performance include the followings: Materials of the milling jars and media. Milling media size Milling time Grinding speed Ball to powder ratio MSE...

Laboratory Furnace Applications and Selections

Posted by Chia-yu Chen on

From sintering to annealing and debinding to calcining, furnaces play a vital role in laboratories. As all applications are different, you will need to alter furnace configurations and temperature ranges to ensure accurate results. Some applications may even require inert gas, so a furnace that is compatible with gases is necessary. MSE Supplies offers various types of furnaces, such as muffle furnaces, tube furnaces and chamber furnaces. Learn more about the types of lab furnaces and various lab furnace applications. What Is a Laboratory Furnace? A laboratory furnace enables technicians to heat samples over an extended period. They are typically...

Polishing & Grinding Cloths from Metkon Technologies

Posted by Joey Oliva on

Any high quality microscopic or analytical sample preparation usually requires several phases of grinding and polish to bring out the best surface possible. Whether a sample is metallographic, petrographic, or somewhere in-between, Metkon Technologies' polishing & grinding cloths sold by MSE Supplies offer a vast array of performance capabilities that are sure to meet your specimen preparation needs. These cloth pads do not have their own internal abrasive, so one must be added in the form of a diamond suspension/lubricant, also available through MSE Supplies. The end-user can choose the grain size they would like to add to a pad; however, once an abrasive...

Physical Vapor Deposition-How to Choose a Suitable Method to Deposit a Thin Film

Posted by Chia-yu Chen on

Physical vapor deposition (PVD) is one of the vacuum deposition methods, which is widely used for surface coatings and thin film fabrication. The most common PVD processes are sputtering and evaporation. To determine a suitable method for deposition, understanding basic deposition principles can be very helpful. Sputtering deposition Sputtering deposition is widely used for metals and ceramics (e.g., oxides and nitrides). In the sputtering process, the target material or cathode is bombarded by high energy ions sputtering off atoms. The ejected atoms are then deposited on the substrate surface. To produce the high energy ions, DC or RF are used as...

ITO (Indium Tin Oxide)

Posted by Chia-yu Chen on

Indium tin oxide coated glass is the most popular substrate for Transparent and Conductive Oxide (TCO) substrates. ITO is widely used in electrodes for photovoltaic/solar cells, LCD display etc. ITO glass can be fabricated via physical vapor deposition such as sputter coating or via liquid phase deposition e.g., spin coating and dip coating.  MSE Supplies offers various ITO products including ITO sputtering target for sputter coating and ITO nano powder for emulsions used in liquid phase deposition. MSE Supplies also offers ITO coated glass/PET film with different resistance, size and customized ITO patterns. Many published papers have used MSE Supplies...
