How to Choose the Right Blast Nozzle for Wet Abrasive …

Some manufacturers produce their own composite carbide nozzles which are even harder than boron carbide. Nozzles are not cheap to replace. One benefit of vapour abrasive blasting is that your nozzles will last up to 3x longer than a dry blasting nozzle because the particles are enclosed in a lubriing water jacket, which reduces friction between the abrasive and the nozzle lining.

This material is also compatible with silicon carbide fiber morphologies. Issue Micro-abrasives: ultra-fine lapping and polishing surfaces for semiconductor appliions and other processes, such as chemical-mechanical planarization (CMP), demand extremely fine, uniform, sub-micron particles.

Particle Size and Shape of Abrasives - HORIBA

Laser Diffraction The laser diffraction technique is capable of covering almost all of the abrasive size ranges and is quicker and easier than either sieves or sedimentation. For this reason laser diffraction is becoming more popular as a technique. Results from the LA-960 laser diffraction analyzer for diamond and silicon carbide abrasives are shown below.
