Products Description
Specification
Colloidal silica, also known as colloidal silica, is a colloidal solution of silica colloidal dispersed in water or organic solvents, the particle size from a few nanometers to tens of nanometers, milky translucent, with good chemical uniformity, high purity, fine particles, high activity advantages, often used in ceramic materials binder to improve the strength of the blank, promote the sintering of matrix materials
Application：
Colloidal silica is a kind of solid particle with nanometer size, which is composed of silicon source and surfactant. It has high specific surface area, high dispersion and excellent stability, and is widely used in food, medicine, chemical industry and other fields.
the use of colloidal silica
1. Food additives
Colloidal silica as a food additive is mainly used to prevent food caking, improve fluidity, enhance stability and extend shelf life. In addition, it can also be used as a clarifying agent, bleach and emulsifier.
2. The field of medicine
Colloidal silica is widely used as an additive in tablets and capsules in the pharmaceutical field. It can increase the stability and bioavailability of the drug, improve the absorption and release performance of the drug, and also increase the adhesion and targeting of the drug in the body, improving the therapeutic effect.
3. Chemical industry
Colloidal silica can be used as catalyst, adsorbent and separation agent. It can increase reaction rate, enhance reaction selectivity and enhance catalyst stability. In addition, it can also be used as a filler for flexible composite materials to improve the strength and toughness of the material.
