Lime and Limestone in Agriculture | Graymont
Aluminum increases in solubility as soil pH decreases. High levels of aluminum can restrict root and plant development. In addition to the above qualities, ag-lime has been shown to increase herbicide effectiveness, increase nutrient availability to plants and add calcium to soil.
Boron appears with calcium, aluminum and manganese in the borosilie manganaxinite. With beryllium, boron forms the oxide mineral Haergite . Zirconium appears with boron in the oxide mineral painite , which is very hard (MH =8) and sometimes of gem quality.

Aluminum | Encyclopedia
Aluminum oxide, Al 2 O 3, often called alumina, does not melt until over 3, 632 F (2, 000 C), and is used to line furnaces. Other forms of alumina are corundum and emery, which are very hard and are used as abrasives. Among the many other mineral forms

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide
Calcium is reactive and, for a metal, soft (with difficulty, it can be cut with a knife). In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal burns

Manganese metal is produced from the manganese(III) oxide, Mn2O3, which is found in manganite, a manganese ore. The manganese is reduced from its +3 oxidation state in Mn2O3 to the zero oxidation state of the uncharged metal by reacting the Mn2O3 with a reducing agent such as aluminum or carbon.
Oxide Ceramics – Aluminum Oxide (Al2O3)
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. CeramTec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
