This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [ 1] The following findings are required for substances to be placed in this schedule: [ 2] The drug or other substance has a high potential for abuse. The drug or other substance has a currently accepted medical use in ...
The Schedule 2 list is one of three lists. Chemicals that can be used as weapons, or used in their manufacture, but that have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 3 is used for chemicals that also have widespread industrial uses. The use of Schedule 1, 2, or 3 chemicals as weapons is banned ...
Schedule 1 substances shall not be produced, acquired, retained or used at all by State Parties outside their territories, except in limited quantities for research, medical or protection purposes. [5] Schedule 2 [6] contains substances that pose a significant risk for use as a chemical weapon, or as a precursor of a substance from List 1 or ...
Aluminium oxide in its powdered form. Al 2 O 3 is an electrical insulator but has a relatively high thermal conductivity ( 30 Wm−1K−1) [ 2] for a ceramic material. Aluminium oxide is insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an ...
Infobox references. Aluminum silicate (or aluminium silicate) is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al 2 O 3 and silicon dioxide, SiO 2 which may be anhydrous or hydrated, naturally occurring as minerals or synthetic. Their chemical formulae are often expressed as xAl 2 O 3 ·ySiO 2 ·zH 2 O.
Aluminium oxides. Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium (III) oxide (aluminium oxide), ( Al2O3 ), the most common form of aluminium oxide, occurring on the surface of aluminium and also in crystalline form as corundum, sapphire, and ruby.
It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [1] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
Corundum. Corundum is a crystalline form of aluminium oxide ( Al2O3) typically containing traces of iron, titanium, vanadium, and chromium. [ 3][ 4] It is a rock -forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [ 7]
