An aluminate is a compound of alumina and a metallic oxide. Since aluminum is similar to the nonmetals, it has some nonmetal characteristics and some metal characteristics. Its oxide is amphoteric and it dissolves in both bases and acids. When dissolved in bases it forms the aluminate ion. Minerals like chrysoberyl are sometimes called aluminates, although they are usually classified as mixed oxides. As minerals, aluminates are much less common than aluminosilicates.

Sodium aluminate is used in water treatment and papermaking industry. However, production of sodium aluminate is chiefly for the manufacture of sodium aluminosilicates and to coat titanium dioxide pigments to improve the pigment's resistance to ultraviolet light. In water treatment it is used as an adjunct to water softening systems, as a coagulant aid to improve flocculation, and for removing dissolved silica and phosphates. In construction technology, sodium aluminate is employed to accelerate the solidification of concrete, mainly when working during frost. Sodium aluminate is used in the paper industry for fire brick production and alumina production.

Potassium aluminate can replace Sodium Aluminate for applications with Sodium sensitivity. Potassium Aluminate is a basic coagulant as a result its use in acidic wastewaters lowers the cost of the treatment compared to the use of other coagulants. Potassium Aluminate is also used as a dyeing and printing mordant, as a paper sizing, as an accelerant in the setting of concrete.

Calcium aluminates are used in the manufacture of refractories and cements. Due to its relatively high cost calcium aluminate cements only under specific circumstances; when rapid strength development is required at low temperatures, when high chemical resistance is necessary, when refractory concretes need to maintain strength at high temperatures, and when as a component in blended cement require ultra-rapid strength development and controlled expansion.

Purities include 99%, 99.9%, 99.99%, 99.999% and 99.9999% which are sometimes referred to as 2N, 3N, 4N, 5N and 6N.

Physical properties may include nanopowder, nano particle, submicron, - 325 mesh, rod, foil, and high surface area carbonate with particle distribution and particle size controlled and certified. We produce larger - 40 mesh, - 100 mesh, -200 mesh range sizes and < 0.5 mm, 2 mm, 5 mm and other mm size shot, granules, lump, flake and pieces, too.
