How to Calculate the Percentage of Sodium Silicate 2:1 in a Solution Using Silicon PPM Data
History
Sodium silicate, also known as water glass, has a long history dating back to the early 19th century. It was first used by artisans and craftsmen for a variety of applications. Over time, its production methods and uses have evolved significantly, leading to its widespread use across various industries.
Properties
Sodium silicate is a water-soluble silicate compound. It is characterized by its SiO2:Na2O weight ratio, which can range from 2:1 to 3.75:1. This ratio is crucial in determining the specific properties and applications of sodium silicate. The SiO2:Na2O ratio can be converted to molar ratios using a factor of 1.032, resulting in the above-mentioned range.
Production
Liquid Phase
One of the common methods for producing sodium silicate is through the liquid phase process. In this method, sodium carbonate and silica sand are dissolved in water at high temperatures, and the resulting solution is cooled and concentrated to form sodium silicate. This process can be fine-tuned to achieve specific SiO2:Na2O ratios, thus allowing for customization of sodium silicate to meet various industrial needs.
Solid Phase Thermal Process
The solid phase thermal process involves the reaction of sodium carbonate and silica sand in a kiln at high temperatures. This method results in the formation of sodium silicate with a specific SiO2:Na2O ratio. The process is typically used for producing higher quality sodium silicate due to its lower residual soda content compared to the liquid phase process.
Uses
Numerous applications of sodium silicate exist across various industries:
