Material Type

|
|
| ||
| Material Type: | |||
| Your choices are... | |||
| Activated Alumina | Activated alumina is an aluminum oxide that is highly porous and exhibits tremendous surface area. Activated alumina is resistant to thermal shock and abrasion and will not shrink, swell, soften, or disintegrate when immersed in water. | ||
| Activated Carbon | Roasting organic material until it decomposes into granules produces activated carbon. Coconut shells, wood, and bone are common sources. Activated carbon is available in a variety of particle sizes. | ||
| Calcium Oxide | Calcium oxide, also known as quick lime, is a highly reactive chemical that reacts with water or carbon dioxide to form calcium hydroxide or calcium carbonate. | ||
| Calcium Sulfate | Anhydrous calcium sulfate is commonly used as a desiccant that changes color when it is hydrated. | ||
| Clay / Silicates | Clay minerals such as montmorillonite, kaolinite, bentonite, veremiculite, or other aluminum silicate or calcium silicate materials. | ||
| Molecular Sieve / Zeolite | Molecular sieves are micro porous crystalline solids with well-defined structures. Generally they contain silicon, aluminum, and oxygen in their framework and, water and/or other molecules within their pores. Many occur naturally as minerals and are mined in many parts of the world. Others are synthetic and are made commercially for specific uses. Zeolites are the most common type of molecular sieve. | ||
| Polymer / Organic | Polymers and plastic materials that are organic, synthetic, or processed polymers. | ||
| Silica Gel / Silicon Dioxide | Silica gel is a matrix of hydrated silicon dioxide used with adsorption equipment. Silica, or silicon dioxide (SiO2), is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel can adsorb about 40% of its weight in moisture and can take the relative humidity in a closed container down to about 40%. To reuse silica gel, simply heat it to above 300ºF (150ºC) until the moisture is evaporated away. | ||
| Sodium Carbonate | Sodium carbonate is a chemical compound that contains the oxyanion carbonate. Carbonate is composed of three oxygen atoms bound to a single carbon ion and contains an overall charge of -2. The anion, sodium, carries a charge of +1. It can be used as a water softener or absorbent cleaner. | ||
| Specialty / Other | Other unlisted, specialized, or proprietary material. | ||

| |||
| Form | |||
| Your choices are... | |||
| Bulk / Raw Material | Sorbent materials are in the form of bulk solids, pellets, flakes, chunks, crushed material, or granules. | ||
| Pouch / Sack | Sorbent material is contained in a pouch or sack in order to prevent mixing of the material with the product to be treated. | ||
