摘要：It has been discovered that carbonate powders and bicarbonate powders areuseful to increase the pH and corrosion resistance of high-density brines, such as zincbromide brines, without significantly reducing their densities. The carbonates and/orbicarbonates should be water-soluble and may be sodium, potassium, magnesium and/orammonium carbonates and/or bicarbonates and the like. The carbonates and/orbicarbonates are easily added in powder or other finely divided solid form.
