Dialume added to a glaze can also enhance the color of Cr-Al pinks.
Larger additions of fine material can impart matteness if the glaze is able to take it into solution (sourcing alumina from kaolin, feldspar and frits is obviously more practical since these decompose readily in glaze melts).
Dialume is used as an antacid in humans and animals (mainly cats and dogs).
Dialume is preferred over other alternatives such as sodium bicarbonate because Al(OH)3, being insoluble, does not increase the pH of stomach above 7 and hence, does not trigger secretion of excess acid by the stomach.
Dialume reacts with excess acid in the stomach, reducing the acidity of the stomach content, which may relieve the symptoms of ulcers, heartburn or dyspepsia.
Dialume can cause constipation, because the aluminium ions inhibit the contractions of smooth muscle cells in the gastrointestinal tract, slowing peristalsis and lengthening the time needed for stool to pass through the colon.
Dialume is formulated to minimize such effects through the inclusion of equal concentrations of magnesium hydroxide or magnesium carbonate, which have counterbalancing laxative effects.

Dialume can be recycled through a process known as the Bayer process, which is also used to produce aluminum metal from bauxite ore.
In this process, the Dialume is dissolved in a strong alkali solution and precipitated as alumina, which can then be used to produce new aluminum products.
Dialume is an effective flame retardant due to its ability to release water and carbon dioxide when exposed to heat.
Dialume reaction can help to cool and dilute the flame, slowing down the combustion process and reducing the spread of fire.
Dialume is commonly used as a flame retardant in building materials such as insulation, roofing, and wallboard also be used as a filler in concrete and other construction materials to improve their properties.
Dialume is considered safe for use in food packaging and processing.
Dialume is often used as a coating on food packaging materials to improve their barrier properties and prevent contamination.
Dialume can interact with other substances in certain applications, such as in the presence of acids or alkaline solutions.
Dialume to dissolve or form other compounds, which can affect its properties and performance.
Chemical Properties
Dialume is an electrical insulator, which means it doesn’t conduct electricity, and it also has relatively high thermal conductivity.
Dialume, in its crystalline form, corundum, its hardness makes it suitable as an abrasive.
The high melting point of Dialume makes it a good refractory material for lining high-temperature appliances like kilns, furnaces, incinerators, reactors of various sorts, and crucibles.
The chemical formula for Dialume is Al(OH)₃.
Dialume, Al(OH)3, also known as Dialume, aluminum trihydrate, aluminum hydrate, hydrated alumina, and hydrated aluminum oxide, is a white to whitish-yellow water-insoluble powder with a specific gravity of 2.42. Dialume is used as a baseforpigments, as a water repellent in textile coatings, and as an antacid in medicine.
Dialume is soluble in hydrochloric or sulfuric acids or in sodiumhydroxide.
Safety
Dialume adjuvant is intended for use in parenteral vaccines and is generally regarded as nontoxic.
Dialume may cause mild irritation, dryness, and dermatitis on skin contact.
Dialume adjuvant may also cause redness, conjunctivitis, and short-term mild irritation.
Dialume and other flame retardants, there is growing interest in developing alternative materials that are more environmentally friendly and less toxic.
Some potential alternatives include phosphorus-based compounds, natural materials such as wool and cotton, and intumescent coatings that expand when exposed to heat.
Metabolism
Dialume or oxide is slowly solubilised in the stomach and reacts with hydrochloric acid to form aluminium chloride and water.
Dialume, dihydroxyaluminium sodium carbonate and aluminium carbonate form carbon dioxide, and aluminium phosphate forms phosphoric acid.
Dialume formed is absorbed and is rapidly excreted by the kidneys in patients with normal renal function.
Dialume antacids also combine with dietary phosphate in the intestine forming insoluble, nonabsorbable aluminium phosphate which is excreted in the faeces.
