Can silica gel be modified?

Can silica gel be modified?

Of course! Silica gels can be modified in several configurations including, but not limited to pH adjustment, ionic stabilization, surface charge, and surface modification.

Is silica gel bad for the environment?

Because silica gel products are composed of amorphous silica and water, they are among the most environmentally friendly industrial chemical products.

Are there any special health hazards?

Silica gel products are aqueous dispersions of amorphous silica. Silica gel is not classified as a harmful ingredient, but it is slightly irritating. Since these products can have a drying effect on the skin, protective gloves should always be used. In case of skin contact, rinse the contact area with plenty of water. Safety glasses are always recommended. In case of accidental contact with eyes, rinse with plenty of water and seek medical attention.

Colloidal silica/Silica Sol with Large Particle Size

Colloidal silica/Silica sol is a kind of colloid that is formed by nm-grade particles of SiO2, dispersed in water. It is odorless, tasteless and nontoxic and its chemical molecular formula is mSiO2·nH2O.

1. The colloid particles are minute, and the particle size can be controlled according to customers' requirements.

2. Colloidal silica/Silica sol has relatively large specific surface area, and high heat-resisting performance (1500-1600"C).

3. With low viscosity, it can soak the places where water soaks; therefore, it presents excellent dispersion and permeability.

4. When the moisture contained in silica sol is evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.

Product application: ceramics, sapphire polishing, gallium arsenide, silicon wafer polishing, cement curing agent, refractory materials, etc.
