  • Nanotopics: High Resolution Reflected Light Microscopy to Determine Filler Micro-Dispersion
    . In this method a diamond or glass blade is used to cut a. sample the width of only a micron or less. This is usually done after flash freezing in liquid. nitrogen. This is the method that would be used for solid polymers. Other methods include. dehydration and ion beam milling, neither of which
  • Analysis of Trace Elements in Tungsten Carbide using the Teledyne Leeman Labs Prodigy DC Arc
    Tungsten carbide is a fine gray powder with a melting point of 2870ÂșC and a hardness of 8.5-9.0, surpassed in hardness only by diamond materials. Tungsten carbide is produced via reaction between tungsten metal and carbon at high temperatures; it is not a naturally occurring compound. The hardness
  • Low Defect Ceria-Based Slurries: Novel Selectivity, Slurry Characterization, and Polishing Mechanisms (.pdf)
    distribution analyzer. Infrared spectra were obtained. on a Nicolet Magna 560 FTIR equipped with a diamond ATR probe and were auto-baseline. corrected. Distortions due to diamond in the region of 1800-2400 cm-1 were blanked out. 5.3 Polish Results. Polishing was done on an Applied Materials 200mm Mirra
  • MICRO: green mfg
    was performed using a 100-grit diamond disk at a pressure of 0.5 psi (3.5 kPa), a rotational velocity of 30 rpm, and a disk sweep frequency of 20 per minute. Conditioning was followed by a 2-minute pad break-in step using a silicon dummy wafer. Other experimental conditions included: * In situ conditioning
  • Substrates and Discs
    diamond core drills and diamond bandsaws. Craftsmen slice the rods or sections into discs that are roughly the size of the final component. The roughly plane-parallel surfaces of the discs are ground with a coarse diamond slurry to bring the optical surfaces into approximate conformance with the final
  • Particle Size and Shape Analysis of Abrasives in Solar Industry (.pdf)
    . Conclusion. Abrasives are used in solar industry to prepare wafer. Carbide and diamond dispersed. in liquid media are usually needed in this application for their hardness. During the slicing process the particle size is decreasing and particles are rounder. Control the particle size in the carrier liquid
