Quick lime is often used in:
- Steel industry: The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel
- Other industry: Small quantities of quicklime are used in other processes; e.g., the production of glass, calcium aluminate cement, and organic chemicals
- Cement industry: Cement: Calcium oxide is a key ingredient for the process of making cement.
- Paper industry: Paper: Calcium oxide is used to regenerate sodium hydroxide from sodium carbonate in the chemical recovery at Kraft pulp mills.
Petroleum industry: Water detection pastes contain a mix of calcium oxide and phenolphthalein. Should this paste come into contact with water in a fuel storage tank, the CaO reacts with the water to form calcium hydroxide. Calcium hydroxide has a high enough pH to turn the phenolphthalein a vivid purplish-pink color, thus indicating the presence of water
