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.

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.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Excellent mineral sunscreen for sensitive skin.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
I’ve been using the Blue Lizard Sensitive Mineral Sunscreen, and it’s become a staple in my routine. As someone with sensitive skin, I really appreciate that it’s fragrance-free and uses zinc oxide, providing great protection without causing any irritation or breakouts. It goes on smoothly, isn't overly greasy, and the water resistance holds up well for outdoor activities. The smart cap technology is a nice touch, too. Highly recommended if you’re looking for effective, non-irritating sun protection.

No chemicals that will be harmful!
Size: 5 Fl Oz (Pack of 2), Set name: Tube - 5 oz. 2-Pack
Ordered this mineral sunscreen looking for something simple and effective, and it’s been a solid option so far. The zinc oxide formula is the main reason I went with it. It doesn’t rely on the same chemical ingredients found in a lot of other sunscreens, which is a big plus if you’re trying to avoid that. It feels like a cleaner option overall. Coverage is good. It spreads evenly and holds up well, even with some water exposure. I’ve used it outdoors for extended periods, and it does its job without needing constant reapplication. It does leave a slight white cast at first, which is pretty typical with mineral sunscreens, but it fades in as you rub it in. Not completely invisible, but manageable. After a few uses, what stood out most is that it doesn’t have a strong smell and doesn’t irritate the skin. It just works without a lot of extras. Compared to standard chemical sunscreens, this feels more straightforward and less harsh, especially for regular use. For the price, it’s a great value. You’re getting strong sun protection without the added ingredients some people try to avoid. If you’re looking for a mineral-based sunscreen that’s effective and a bit cleaner in formulation, this is a solid choice.

Great mineral sunscreen that actually works
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
Blue Lizard Sensitive Mineral SPF 50 has become my daily go-to. It goes on smooth, doesn’t leave a weird white cast like some mineral sunscreens, and gives solid protection. I like that it’s 100% mineral with no harsh chemicals and has organic aloe vera in it, so my skin feels hydrated instead of dried out. No greasy feeling, no strong scent, and it holds up well even when I sweat a bit. Been using it for a few weeks now and it performs exactly how I want. Small bottle but a little goes a long way. Definitely recommend if you want a simple, effective mineral option.
