Dispersing Aluminas for the Refractory Market

Almatis' dispersing aluminas are vital in optimizing refractory low cement castables, which contain fine and ultra-fine particles like calcium aluminate cement, reactive aluminas, and silica fume. Our additives ensure uniform distribution of these matrix components when mixed with water, optimizing particle size distribution for minimal water usage and ideal rheology.

These aluminas outperform traditional dispersing agents such as phosphates by significantly reducing water demand, which in turn enhances mechanical properties and corrosion resistance.

A unique feature of Almatis dispersing aluminas is their ability to adjust the setting time of castables to meet specific application needs and climate conditions without sacrificing final strength - an issue common with other additives.

Our product range includes:

For silica-free castables with alumina fines: ADS 1, ADS 3, ADW 1. 
For fumed silica-containing castables with alumina fines: M-ADS 1, M-ADS 3, M-ADW 1.
