Guangdong Well-t Nanotech Co., Ltd.

In the most general terms colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area. A charge is then induced on the silica nanoparticle surface that allows the silica particles to repel one another and form a stable dispersion, or colloid. Colloidal Silica is readily soluble in water in all proportions. It has a low viscosity, which is comparable to that of water. The individual silica particles get thoroughly dispersed in water. Ubiquitous products are characterized by their exceptionally low viscosity and excellent stability. Ubiquitous manufactures various brands of Colloidal Silica which are tailor-made for applications ranging from investment casting to catalysts manufacturing Grades Colloidal Silica is available in many grades. The concentration of Silica varies from 20 wt% to 50 wt%. The particle size range produced by Ubiquitous is between 7-35 nanometers. Chemical Composition of Colloidal Silica Our Brands, U Family The U have for long been our greatest strengths, with clients lauding the quality and consistency of the products. The U can be used for a host of applications

1) Sodium Silicate Liquid Liquid Sodium Silicate is a major compound used for formulating chemicals like silicate gel and precipitated silica. Apart from this, Sodium Silicate Liquid has an extensive usage in ceramic industry, paper industry, detergent industry as well as electrodes manufacturing companies. We cater to varied requirements of the clients by making available the Liquid Sodium Silicate in different grades like Neutral Sodium Silicate Liquid and Sodium Silicate Alkaline Liquid. Properties Its solution is alkaline. If add strong acids, weak acids and even electrolytes, it will hydrolyze and precipitate silica when it is heated or at room temperature. Packaging and storage It is packaged with clean iron drum, plastic drum or tank truck and sealed. Alkaline Grade Specifications Wt.
