We have studied nucleation and crystal growth of calcium carbonate on hard surfaces, i.e. stainless steel and silica, at different temperatures, in relation to the corresponding bulk processes, using scanning electron microscopy (SEM), X-ray diffraction (XRD), and ellipsometry. In the bulk solution, a mixture of all three calcium carbonate …

Chromium increases the corrosion resistance of steel, and a minimum of 12% chromium is necessary to produce a stainless steel. The best known of the stainless steels contains about 74% iron, 18% chromium and 8% nickel (known as 18-8 stainless). Stainless steel is perhaps most familiar as kitchenware (sinks, kettles and cutlery).
