Silicon Nitride Grinding Media Balls

By -
Image
  Innovacera Silicon Nitride Grinding Media Balls was made by 3 forming way: titration, roll and CIP (cold isostatic pressing ) forming and they were gas pressing sinetering in 1800～2100℃.The purity of silion nitride is 99% and generally if the diameter size is more than 3mm, we will choose the CIP forming way. Silicon nitride grinding balls have excellent features of chemical inertness, low friction and heat generation, electrical insulation, non-magnetic, high strength and corrosion resistance. Compared with other grinding media, the  silicon nitride (Si₃N₄)  milling media balls improves energy efficiency, reduces mechanical wear and ultra-fine grinding and dispersion. It is a ideal grinding media when high wear resistance, minimal contamination and less abrasion is required such as semiconductor slurries, pharmaceutical dispersions, battery material milling. Our silicon nitride media balls main size is 0.2 mm – 20 mm. Si3N4 Milling Ball General Size: Model Size (mm) IN...

Ceramic Vacuum Brazing: Unlocking the Potential of Ceramic to Metal Bonds in High-Tech Applications

By -
Image
  Ceramic materials, with their high melting points and excellent insulating properties, present significant challenges when it comes to joining them with metals. Traditional welding methods often struggle to create strong and reliable bonds. However, advancements in joining technologies have introduced Vacuum Brazing as a highly effective solution. This process not only overcomes the limitations of ceramics but also leverages the benefits of both materials to create composite components.     Vacuum brazing is particularly advantageous due to its ability to join ceramics and metals at high temperatures in a vacuum environment, which minimizes oxidation and other unwanted reactions.  Ceramic-to-metal sealing  process often involves the use of a brazing filler metal, which can be tailored to the specific materials being joined. One such technique is Active Metal Brazing, where a reactive element in the filler metal, such as titanium in Ag-Cu-Ti, activates the cera...

What are the Key Factors To Consider in Boron Nitride Atomizer Nozzle Design

By -
Image
  Boron nitride atomizer nozzles   for powder metal atomization play a crucial role in the atomization process. These nozzles are responsible for converting molten metal into fine powder particles, which are then used in various industries such as automotive, aerospace, and electronics. There are different types of boron nitride atomizer nozzles used in powder metal atomization, including gas atomizers and water atomizers. Gas atomizers use high-pressure gas to disintegrate a molten metal stream into tiny droplets, which solidify into powder particles as they cool down. Water atomizers, on the other hand, use water jets to break up the molten metal stream into powder particles.   The design and construction of boron nitride atomizer nozzles are critical for ensuring efficient and effective atomization. Some key factors to consider in boron nitride atomizer nozzle design include: Nozzle geometry:  The shape and size of the nozzle play a role in determining the droplet...
