Products in Construction Chemicals: Aluminum Compounds

USALCO Sodium Aluminate (Granular) is a white powder that easily dissolves in water and is the dry form of sodium aluminate. It is produced by mixing alumina trihydrate with sodium hydroxide to create a solution, which is then solidified by removing excess moisture. This product does not contain any stabilizing agents.

USALCO Sodium Aluminate Solution (38%) is an economical source of highly reactive alumina manufactured by dissolving alumina tri‐hydrate (ATH) into sodium hydroxide and water. USALCO 38 is also stabilized to prevent alumina from precipitating. The use of only stringently selected raw materials and state‐of‐the‐art manufacturing practices ensures that USALCO 38 is of the highest quality. USALCO 38 meets the specifications of the American Water Works Association Standard B405‐16 and complies with the requirements of NSF/ANSI/CAN 60: Drinking Water Treatment Chemicals ‐Health Effects at a maximum dosage of 105 mg/L.

USALCO Sodium Aluminate Solution (45%) is an economical source of highly reactive alumina manufactured by dissolving alumina tri‐hydrate (ATH) into sodium hydroxide and water. USALCO 45 is also stabilized to prevent alumina from precipitating. The use of only stringently selected raw materials and state‐of‐the‐art manufacturing practices ensures that USALCO 45 is of the highest quality. USALCO 45 meets the specifications of the American Water Works Association Standard B405‐16 and complies with the requirements of NSF/ANSI/CAN 60: Drinking Water Treatment Chemicals ‐Health Effects at a maximum dosage of 89 mg/L.

Evonik's AP-22 is a multipurpose rehydratable alumina that works in multiple applications. It is an activated alumina that can be used as a starting material for formed alumina, extrudates, and as a general adsorbent. Its wide range of applications includes serving as a binding agent, alumina-forming agent, adsorbent, desiccant, viscosity modifier, and anti-shrinkage agent for cements.

Micronized Products Supersilk is an aluminum silicate mineral. It is characterized by its softness and platy or lamellar physical structure. Supersilk offers good dry brightness (whiteness) and chemical stability.

SEPASIL® is for industrial use, mighty, workable silica sand deposits are of decisive importance. Nevertheless, chemical purity and constancy are not enough in order to apply silica directly as a raw material. In Quarzwerke plants silica sands are thoroughly prepared. The raw material has to pass exten-sive cleaning-, classification-, drying- and iron-free grinding processes in order to produce silica sands, flours and powders. For the production of silica flours and -powders with a defined grain size distribution separation processes are required in addition to iron-free grinding. Quarzwerke are able to produce silica powders with grain sizes down to 1 μm due to a fine-tuned combination of grind- and classification technology. Another refining step is the surface-treatment with silanes or silan-based substances which can be adjusted to the respective application.

Dolomite 500# is a double carbonate of Magnesium and Calcium (CaCO3. MgCO3) Theoretically, it contains 21.7 MgO and 30.4 % CaCO3 and the remaining being CO2. How ever in nature much variation takes place in the composition. It is sedimentary origin and is supposed to have been formed due to alteration of Calcium Carbonate sediments or rocks, by seawater rich in magnesia.

Hammond Group Ceraflux, also known as lead alumina bisilicate, is specially formulated for use in pottery and wall-tile glazes. It is also used is low-loss dielectrics and reflective highway signs. Lead bisilicate is extremely resistant to leaching by dilute acids, including gastric juices, which reduces its toxicity and offers the maximum safety of any of the lead products.
