Do you know which common inorganic binders are used in refra

First, water glass

Water glass, commonly known as "sodium silicate" and "sodium silicate", is a highly complex dispersion system. The water glass can be hardened by heat or a hardening agent can be added to cause chemical curing. An aqueous solution of sodium silicate is commonly referred to as water glass, and sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid in a system in which water is used as a dispersing agent. Solid sodium silicate is a colorless, slightly colored transparent or translucent glass block. The form is divided into liquid, solid and water quenching. In theory, these substances are called "colloids." Water glass is commonly known as sodium silicate, and its main component is silicon. Ordinary sodium silicate is a slightly light blue block or granular solid, which is a slightly colored transparent or translucent viscous liquid after high temperature and high pressure dissolution. The main type of silicate binder as the amorphous refractory binder is alkali metal silicate, which is called water glass.

 

Water glass is widely used in refractory materials, acid (siliceous, waxy), neutral (clay, high aluminum), alkaline (magnesium, magnesium chrome, magnesium aluminum), can be used for shaping and amorphous;

Second, silica sol

Silica sol is a binder for advanced refractory materials. For shaped refractories, silica sol binders act to increase the strength of the body, reduce the sintering temperature, and broaden the sintering range. For the amorphous refractory material, the silica sol acts as a bonding agent. The correct blending of the silica sol and the chemical admixture can significantly improve the fire resistance by substantially reducing the cement blending without affecting the coagulation and solidification rate without reducing the drying strength. The effect of high temperature properties of the material. For example, an ultra-low cement refractory castable is provided.
