The Scientific Name For The Substance Is Alumina Trihydrate (ATH), And Its Chemical Formula Is (AI2O3•3H2O)

 

Alumina Trihydrate

When used as a filler, extender pigment, and bodying agent in oil- and water-borne paint, Alumina Trihydrate (also known as aluminium hydrate, alumina hydrate, aluminium hydroxide, or ATH) has a minimal impact on the colour of the paint. This powder, which has an 8-micron median particle size and ranges in colour from white to tan, can be added to paint to give the paint film more transparency.

Due to its adaptability and affordability, Alumina Trihydrate is the most popular flame retardant in commercial coatings. It is suitable for use in a variety of paint binders when processing temperatures are lower than 220 °C. ATH has a low abrasiveness, is non-toxic, halogen-free, and chemically inert. Acid resistance and smoke suppression are added advantages. At around 220 degrees Celsius, ATH starts to endothermically breakdown, releasing roughly 35% of its weight as water vapour.

According to Coherent Market Insights, The global Alumina Trihydrate Market is estimated to reach US$ 6.5 Billion by the end of 2027.

Alumina Trihydrate slows down burning by acting as a heat sink, delaying pyrolysis. Moreover, the water vapour generated has the function of neutralising harmful fumes and combustion gases. Over 100 million tonnes of alumina trihydrate are produced annually, almost entirely using the Bayer process. Bauxite (aluminium ore) is dissolved in sodium hydroxide at high temperatures using the Bayer process. After the solids are heated through, alumina trihydrate is then separated from them. After the alumina trihydrate has been removed, the solids are extremely hazardous and pose environmental problems.

Silver-white Aluminium is an element that is in group 13 of the periodic table. Aluminum is a perfect material for engineering since it is corrosion-resistant, lightweight, and practical.

Alumina (also known as aluminium oxide or alumina) is created from more than 90% of all generated alumina trihydrate. To restrict and lessen the spread of a flame through a plastic, alumina trihydrate is chemically added to a polymer molecule or mixed in with a polymer. Another application for alumina trihydrate is as an antacid that can be taken orally to buffer the pH in the stomach.
