Product Overview

Silicon dioxide (SiO2) is one of the most abundant, structurally complex, and widely used inorganic materials on Earth. It has many forms, such as quartz crystal, amorphous silicon dioxide solid, silicon dioxide colloid and different kinds of aerogels. Generally, the silicon atoms in silicon dioxide molecules are tetrahedral coordinated, consisting of four oxygen atoms surrounding a central Si atom. In recent years, silica particles have shown significant value in the fields of materials chemistry and physics due to their adjustable size, morphology, microstructure, and easy surface functionalization. Particularly, silica particles functionalized with various functional groups have been widely used in catalysis, adsorption, sensing, and biomedical applications. The synthesis methods of silica particles include: sol gel method, lotion method, precipitation method and chemical vapor deposition method, among which the sol gel method is often used in the laboratory due to the high quality of silica particles. In the sol gel method, tetraethyl silicate (TEOS), tetramethyl silicate (TMOS) and polysiloxane are usually selected as the silicon source, ammonia is used as the catalyst, and is dispersed into a suitable solvent (alcohol or water) to form a solution. By controlling the pH value, the silicon source is hydrolyzed to obtain a sol system, and then aged to gel. Finally, the solvent is evaporated by heat treatment to obtain monodisperse silica nanoparticles, which is also referred to as the Stober method.


Technical Parameter

Status:White powder

 

Application Fields

 

1. Controllable particle size: By adjusting reaction conditions such as reactant concentration, reaction time, temperature, etc., the size of silica particles can be accurately controlled.

2. Good monodispersity: The prepared solid silica particles have good monodispersity, that is, the particle size distribution is relatively uniform.

3. Adjustable surface properties: Its surface chemical properties can be changed through subsequent surface modifications to meet different application requirements. Such as amination (APTES modification) and carboxylation (succinic anhydride modification).


Product Features

1. Chromatographic packing: Due to its good monodispersity and chemical stability, it can be used as a stationary phase packing in high-performance liquid chromatography (HPLC) and gas chromatography (GC).

2. Optical materials: used for preparing optical coatings, anti reflective films, etc., to improve the performance of optical devices.

3. Coatings and Coatings: Enhance the wear resistance, corrosion resistance, and hardness of coatings and coatings.

4. Biomedical field: Surface modification of specific antibodies or ligands for the isolation of specific types of cells. It can also be combined with fluorescent dyes or quantum dots for imaging of cells and tissues.

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!

Fits Well and Reusable. I'm Happy.
Size: 9.6" x 11.1" x 2.2", Size: 9.6" x 11.1" x 2.2"
For less than the price of 2 disposable FRAM CV11671 cabin filters for my 2019 RAM 1500 and this will last forever. If it gets wet, like I've had happen with the paper throw-away filters due to stuff falling off trees in the spring and clogging cowl area water drains and backing up into filter ( yeah, that's a thing ) and can clean and dry this filter and reuse. Great directions came in the box along with a sticker to point out that this is a lifetime filter so someone doesn't throw it away. Do this yourself. Don't let some auto repair shop talk you into it. I was getting tires balanced recently and heard a quote they gave over the phone of $79 to do this. I don't know what kind of vehicle that was for but this ain't rocket science. Don't get ripped off. Now back to this filter. There is no arrow for air flow so I figure it flows well both ways and just put it in with the K and N logo right side up and facing out. It's not a straight in shot the way RAM positioned the opening for the cabin filter slot but was no big deal. Also realize this isn't a perfect square filter ...It's a rectangle so don't try to shove the fat end in and say it doesn't fit. I haven't noticed any air flow differences with the heating / ac system but some people say they do. I'm just happy I don't have to buy anymore disposable filters and can dry this if it gets wet. The cleaning and refresh spray kit is #99-6000 that comes with a 8oz and 12oz bottle and I'm trying to find that cheaper somewhere for when I do clean this thing.

Can’t go wrong with K&N
Size: 9.6" x 11.1" x 2.2"
So I recently took my pickup in to have some recall work done, half way through the process I got a call from the dealership stating I needed a new air filter and that a new one would cost nearly $60. I chuckled and told then to put the old one back in and I immediately came to Amazon and ordered this cabin filter. I’ve used K&N products in the past and have never been sorry, and that is the case with this lifetime filter. Upon installing this filter I noticed an IMMEDIATE difference in air flow into the cabin, it even smelled better. If this filter ever gets dirty Ira easy to clean and reinstall, paying for itself over time. Do yourself a favor and pick one of these up, you will not be sorry.

Fit my Subaru Forester perfectly!
This fit my 2024 Subaru Forester perfectly. The filters exhibited a high quality construction and was packaged well. Installation was easy and saved me a lot of $ vs. having my dealer install an OEM filter.
