Aluminium oxide Aluminium oxide (British English) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al O . It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-AlO as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. AlO is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.

Aluminium sulfacetate Aluminium sulfacetate is a chemical compound of aluminium with formula Al2SO4(CH3CO2)4 . It is a double salt of aluminium sulfate and aluminium acetate. It can be used as a mordant, which is a substance used to set dyes on fabrics that typically contains a polyvalent metal ion like aluminium or iron, In mixtures with basic aluminium diacetate or aluminium sulfacetate, aluminium triacetate has been used as a mordant with alizarin dye. In 1899, Albert Ganswindt recommended that the use of impure sulfacetates that are empyreumatic liquids "should be abandoned" in favour of pure preparations. Empyreuma is an obsolete chemical and medical term referring to "the smell and taste associated with burning vegetable and animal matter", and likely results in this case from the use of pyroligneous acid (wood acid) or wood acid lime in the preparation of the mordant.

KREEP KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks. Its most significant feature is somewhat enhanced concentration of a majority of so-called "incompatible" elements (those that are concentrated in the liquid phase during magma crystallization) and the heat-producing elements, namely radioactive uranium, thorium, and potassium (due to presence of the radioactive K).

Quebecol Quebecol is a polyphenolic chemical compound that has been isolated from Canadian maple syrup. It has the chemical formula CHO and the systematic name 2,3,3-tri-(3-methoxy-4-hydroxyphenyl)-1-propanol. Analysis of maple sap before it is converted into syrup suggests that this compound is not naturally present in the sap but, instead, is formed during extraction or processing.

Dumortierite Dumortierite is a fibrous variably colored aluminium boro-silicate mineral, AlBO(SiO)O. Dumortierite crystallizes in the orthorhombic system typically forming fibrous aggregates of slender prismatic crystals. The crystals are vitreous and vary in color from brown, blue, and green to more rare violet and pink. Substitution of iron and other tri-valent elements for aluminium result in the color variations. It has a Mohs hardness of 7 and a specific gravity of 3.3 to 3.4. Crystals show pleochroism from red to blue to violet. "Dumortierite quartz" is blue colored quartz containing abundant dumortierite inclusions.

Amblygonite Amblygonite is a fluorophosphate mineral, (Li,Na)AlPO(F,OH), composed of lithium, sodium, aluminium, phosphate, fluoride and hydroxide. The mineral occurs in pegmatite deposits and is easily mistaken for albite and other feldspars. Its density, cleavage and flame test for lithium are diagnostic. Amblygonite forms a series with "montebrasite", the low fluorine endmember. Geologic occurrence is in granite pegmatites, high-temperature tin veins, and greisens. Amblygonite occurs with spodumene, apatite, lepidolite, tourmaline, and other lithium-bearing minerals in pegmatite veins. It contains about 10% lithium, and has been utilized as a source of lithium. The chief commercial sources have historically been the deposits of California and France.
