Properties and advantages

Compared to potassium- and sodium silicates, lithium silicates are less soluble once they are dried.

They exhibit less desalting effects compared to potassium- and sodium silicates.

The binding and refractory properties of potassium- and sodium silicates can be improved by mixing them with lithium silicates.
