Aluminium silicate is a type of fibrous material made of aluminium oxide and silicon dioxide, (such materials are also called aluminosilicate fibres). These are glassy solid solutions rather than chemical compounds. The compositions are often described in terms of % weight of alumina, Al 2 O 3 and silica, SiO 2. Temperature resistance increases ...
Activated alumina is also widely used to remove fluoride from drinking water. In the US, there are widespread programs to fluoridate drinking water. However, in certain regions, such as the Rajasthan region of India, there is enough fluoride in the water to cause fluorosis. A study from the Harvard school of Public Health found exposure to high ...

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

Er:YAG lasers can be used in laser aided cataract surgery but owing to its water absorbable nature Nd:YAG is preferred more. [8] Erbium YAG dental lasers are effective for removing tooth decay atraumatically, [9] often without the need for local anesthetic to numb the tooth. Eliminating the vibration of the dental drill removes the risk of ...
However, material silica gel removes moisture by adsorption onto the surface of its numerous pores rather than by absorption into the bulk of the gel. Silica gel is able to adsorb up to 37% of its own weight in moisture in high-humidity environments. [7] This moisture can be released upon heating at about 120 °C (248 °F) [8] [7] for 1–2 ...
TLC Skin Tight is a TV show with each episode following “two people who have lost massive amounts of weight and are about to undergo a full body transformation through skin removal surgery.” [6] “It’s not unusual, says the show, for there to be “up to 50 pounds” of sagging skin following massive weight loss.
