1. Sodium Fluorosilicate Introduction
Sodium fluorosilicate, also known as sodium silicofluoride, is a
chemical compound with the formula Na2SiF6. This odorless, white
crystalline powder is commonly used in various industrial
applications such as water fluoridation, metal surface treatment,
and glass etching. It is a source of fluoride ions and is valued
for its ability to resist acidic conditions. Sodium fluorosilicate
plays a crucial role in enhancing the durability and strength of
materials where it is applied.

3. Sodium Fluorosilicate Applications
The main application areas of sodium fluorosilicate include wood preservation, concrete admixtures, ceramic glazes, and glass manufacturing. In wood preservation, sodium fluorosilicate can react with the moisture in the wood to generate fluoride with anti-corrosion properties, thereby protecting the wood from pests and mold. In concrete admixtures, it can improve the fire resistance and water resistance of concrete. In addition, sodium fluorosilicate is also used in the preparation of ceramic glazes, which can improve the smoothness and hardness of the glaze surface. In glass manufacturing, it helps to improve the transparency and strength of the glass.
The role of sodium fluorosilicate in ceramic tableware mainly
includes the following aspects:
3.1 Enhance coloring performance: Sodium fluorosilicate can be used as a fluorinating agent to promote the reaction of coloring agents and enhance the coloring performance of ceramic tableware glazes by utilizing the fluoride ions it carries. Sodium fluorosilicate is an essential additive in the production of dark and bright colored glazes.
3.2 Reduce surface tension: Sodium fluorosilicate can reduce the surface tension of glaze,
making it easier for glaze to be evenly distributed on the surface
of ceramic tableware. When spraying glaze, the addition of sodium
fluorosilicate can make the glaze adhere more evenly to the surface
of porcelain and reduce bubbles and defects on the coating surface.
3.3 Increase viscosity: Sodium fluorosilicate can be used as a thickener to increase the
viscosity of glazes. When brushing or spraying glaze, a higher
consistency can make ceramic tableware glaze easier to grasp and
operate, and can maintain the thickness and uniformity of the
coating
