nitrate, and sulfate, are soluble in water, whereas carbonates and hydroxides are far less soluble and sulfides, disulfides, subsulfides, and oxides are practically insoluble in water. Alloys of nickel containing more than 13% chromium are to a high degree
Tungsten Carbide Hardfacing from Hardface Technologies
Mig Carbide is unsurpassed in abrasion and impact resistance when applied with POSTALLOY PS-98. This is because softer wires wear away allowing the tungsten carbide to literally fall off the wear surface. POSTALLOY PS-98, with a hardness of up to 60 Rc
The chemistry of cosmetics - Curious
The lipophilic part of the molecule sticks to oil and dirt, and the hydrophilic part allows water to then carry away the otherwise water-insoluble grime. Washing-up detergents work in the same way, although it isn’t generally advisable to wash your hair with dishwashing liquid - they are formulated to remove thick grease from plates, not to gently clean your hair.
