Dry Silica Microspheres

Dry Silica Microspheres are particle size standards used in aerosol research for instrument size calibration, atmospheric testing, drug delivery and CMP slurries. Typically the CMP Slurry dry silica is produced at 800 nanometer diameter, but can be tailored to your size specification. Dry Silica can be ordered in 1 gram volume; or can be special ordered in 1 Kg volume.

A particle size standard is only good if its reliable and repeatable. The Dry Silica Microspheres particles we offer are for this exact thing: giving you a high purity, super uniform particle size standard. You can use these silica particles, which are solid silicon dioxide (𝑆𝑖𝑂2), as a trusted reference for your work with aerosols or CMP slurries. We have a wide range of nanometer diameter silica particles, so if you need 800nm silica particles for sale, we got em. The morphology and batch repeatability is what you can count on.

Engineered for Precision: Unmatched Quality and Versatility

Our dry amorphous silica particles are made in-house by our team to be top-of-the-line. We really focus on the details that matter most for scientists and engineers.

  • Uniform Particle Size: These particles have a very narrow size distribution, often ≤ 10%. This tight monodisperse control means you can trust the standard. If your calibrating an SSIS or LPC, that’s what you need to see.
  • High Purity and Composition: Our particles are made of 100% solid silicon dioxide, nothing else. No weird additives, no surface stuff you didn’t ask for.
  • Broad Size Range: We offer a lot of different sizes, from 100nm to 3.0µm. 
  • Superior Laser Stability: When you hit a particle with a high-powered laser inside a wafer inspection system, you need it to hold up. Our silica doesn’t melt like some other types of particle standards, like PSL spheres, so it won’t mess up your calibration.
  • Packaging Options: You can get these in 1-gram vials for small lab work, or larger bulk volumes for when you really need a lot. We support the nanometer silica powder supplier and dry silica microspheres buy crowd, no matter the size of the operation.

Specialized Applications for Critical Industries

CMP Slurries for Semiconductor Manufacturing

In semiconductor fabrication, CMP is a really critical step. You need a super uniform surface, no scratches. The dry silica microspheres we have are perfect for making CMP slurry. A lot of our customers use our 800nm diameter particles to help make sure their semiconductor polishing is perfect. Our CMP slurry dry silica helps you reduce defect rates, which is a big deal when you are making a lot of wafers.

Aerosol Research and Atmospheric Testing

If your doing research on how particles behave in the air, or atmospheric testing for environmental work, you need a good standard. You use our silica microspheres as a calibration standard for instruments that measure airborne particulate matter. It’s a silicon dioxide powder for aerosol research that you can trust.

Instrument Size Calibration

For SSIS and LPC instruments, you need instrument calibration silica particles. Our silica particle size standards are NIST traceable, so you know they are accurate. We got the data to prove it, and so when your QA person asks, you have the answer.

Why Choose Silica Over Polystyrene Latex (PSL) Spheres?

This is a common question, and it’s a good one. When you are doing instrument calibration, some of the old stuff just doesn’t work so good anymore. Especially with high-powered lasers. Silica microspheres vs PSL spheres, it’s not even a fair fight.

Feature

Silica Microspheres

Polystyrene Latex (PSL) Spheres

Heat Resistance

Withstands high-powered lasers.

Melts under high-power lasers, ruining calibration.

Chemical Stability

Stable across most chemical conditions.

Can degrade in many solvents.

Lifespan

Long shelf life, very reliable.

Can degrade faster, less reliable.

Calibration

Ideal for SSIS and LPC calibration.

Less suited for modern, high-power systems.

Product Variants and Technical Specifications

You want the data, here is the data. If you need a specific size not listed, ask us about it. We can do custom stuff for bulk orders.

Flexible Ordering: From 1 Gram to Bulk Volumes

We sell our silica particle size standard in convenient sizes for lab use, but if you need a whole lot more of the dry silica powder, we can do that too. For 1 kg or larger custom orders, just hit up our customer service team to get a quote. We make it easy, no need for tons of paperwork.

Frequently Asked Questions (FAQ)

How should dry silica microspheres be stored?

Store them in a cool, dry place. Keep the container sealed to prevent moisture from getting in and making clumps.

For sizes over 100nm, our size distribution is typically ≤ 3%. For other sizes, it can be up to 10%. We always provide the exact data for your specific batch.

Yes, our particles are NIST traceable. We have the paperwork to prove it, and we follow the procedures exactly so you can trust the data.
