Calcium permanganate - Revolvy

Calcium permanganate is an oxidizing agent and chemical compound with the chemical formula Ca(MnO). It consists of the metal calcium and two permanganate ions. It is noncoustible, but, being a strong oxidizing agent , it will accelerate the burning of coustible material. If the coustible material is finely divided, the resulting mixture may be explosive.

Calcium nitrate | Ca(NO3)2 - PubChem

Calcium nitrate soln (0.5, 0.25 M), alone or in coination with sucrose, were toxic to stem and flower (carnation) tissue prior to freezing. Calcium nitrate alone offered no protection at -4 deg C. Flowers pretreated with 0.125 M calcium nitrate appeared translucent or water-soaked after 5 days at -4 deg C.

Mineral Scales and Deposits | ScienceDirect

Abstract. Precipitation of mineral deposits is caused by sparingly soluble salts. The primary agents responsible are the carbonates and sulfates of calcium and magnesium with barium salts, silie, and phosphate scaling also causing problems in some industries.

Corrosion tables — Materials Technology

The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.
