Slurries & Suspensions
Slurries and suspensions are abrasive materials consisting of diamond particles suspended in a liquid medium, used in various polishing and lapping applications. They achieve higher material removal rates (MRR) and better surface finish due to the surface characteristics of the diamond.
Hyperion Materials & Technologies offers water-based or oil-based slurries & suspensions mixed with diamond. Diamond is the abrasive agent, and the slurry serves as a vehicle to deliver and distribute the particles evenly on the workpiece surface, which is being polished or lapped. The concentration of diamonds in the slurry varies depending on the application and desired level of abrasiveness.
Hyperion's diamond suspensions are similar to slurries. However, they contain smaller and more uniform particles. The diamond particles are suspended evenly in a liquid medium, usually water or oil, to create a homogenous mixture.

Slurries & Suspensions Applications
Slurries and suspensions are commonly used in semiconductor manufacturing, optics, electronics, and precision machining applications, where high-quality lapping and polishing are required.
Both diamond slurries and suspensions are combined with polishing pads, cloths, or lapping plates to remove material from the surface being worked on gradually. The abrasiveness of diamond particles allows for precise material removal, resulting in a smooth and mirror-like finish. These materials are particularly effective in polishing hard materials like metals, ceramics, glass, and semiconductors.
Hyperion Materials & Technologies also manufactures diamond compound paste for effective lapping, polishing, and finishing solutions.
FAQs about Slurries and Suspensions
Slurries and suspensions are abrasive materials consisting of diamond particles suspended in a liquid medium, used in various polishing and lapping applications.
Diamond slurries and suspensions utilize micron-sized diamond particles as the abrasive agent. Diamonds are known for their exceptional hardness, making them effective for polishing hard materials like metals and ceramics. These products are widely used in electronics, optics, and precision machining applications.
Applying slurries and suspensions for polishing can be an art form. There are many ways to achieve the desired results, although Hyperion offers several rules to achieve optimal performance:
-
Keep the polishing area clean.
-
Dedicate a polishing tool for each grade size. Each tool should be stored in a separate container.
-
Polishing tools gradually become saturated and improve with the use.
-
Clean hands and workpieces carefully between grades
-
Apply the diamond paste to the tool when manually polishing. Apply the paste to the workpiece when the machine is polishing.
-
Polish existing scratch marks at a 90-degree angle. This helps increase stock removal and shows when old marks are gone.
-
High material removal requires high pressure and coarse grits. Finishing polishing requires low pressure and the finest grits.
Slurries and suspensions are abrasive materials used for polishing, lapping, and finishing applications in various industries. They help generate high-quality surface finishes by achieving high material removal rates on different workpieces, including metals, ceramics, glass, and semiconductors.
There are several benefits of using slurries and suspensions for surface finishing. Diamond slurries and suspensions provided improved surface finish, reduced surface defects, increased surface hardness, improved corrosion resistance, and reduced environmental impact.
Slurries and suspensions are very similar; both contain diamond abrasive particles in a liquid medium, either water or oil. The primary difference lies in the size and uniformity of the abrasive particles. Suspensions typically contain smaller and more uniform particles, offering enhanced precision during polishing and lapping.
The industries that benefit from utilizing slurries and suspensions are semiconductor manufacturing, optics, electronics, automotive, aerospace, and cutting tool production. They are extremely valuable for achieving optimal surface finish performance while providing consistent, high-quality lapping and polishing while meeting stringent quality requirements.
Slurries and suspensions can be customized based on particle size, concentrations, and the liquid medium to match specific operating conditions and workpiece requirements. Hyperion will work with customers to customize solutions that best solve customers’ needs to meet better efficiency and performance results.
