Potassium chloride - Wikipedia

Potassium chloride (also known as KCl or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. KCl is used as a fertilizer, in medicine, in scientific applications, and in food processing, where it may be known as E number

A Risk-Based Approach to Stainless Steel

The pH 5 acetate and 1M acetic acid with 1M sodium chloride buffers exposed to 316L stainless-steel passivated coupons affected the passive layer between 72 and 96 hours as determined by electrical pen test and confirmed using copper sulfate and salt spray cabinet testing. Washed and rinsed 316L stainless-steel coupons, passivated with a 10% v/v formulated phosphoric/citric acid detergent at

Rouging - Corrosion

Rouging of stainless steel is the result of the formation of iron oxide, hydroxide or carbonate either from external sources or from destruction of the passive layer. Color variation is a result of the oxide/hydroxide/carbonate type and variations in the water of hydration associated with the corrosion products. These colors range from orange to red to black. Bright red streaks on the surface

Metal Fires – Why Water isn't Always the Best

Metals typically burn at extremely high temperatures, and alkali metals, such as lithium, sodium, potassium, rubidium, and cesium, are particularly reactive with water. When water is applied to an alkali metal fire, the heated water particles can separate into hydrogen and hydroxide. The hydrogen acts as an accelerant (increasing the rate of combustion) and can cause an explosion.
