Quick lime also known as burnt lime, is mainly composed of calcium oxide (CaO) , is an extensively utilized chemical compound across various industries. It exists as a white, highly caustic, alkaline, and crystalline solid at room temperature, exhibiting distinct physical characteristics that make it indispensable in numerous applications. The typical appearance of quick lime is a pristine white powder, which, when contaminated with impurities, can turn a light yellow or gray hue. One notable physical property of this compound is its hygroscopicity, meaning it has the ability to absorb moisture from the surrounding environment. This characteristic is particularly significant in industries where moisture control is crucial.

High activity and high purity quick lime has the following advantages
It has high reactivity and can react rapidly with other substances. For example, in flue gas desulfurization, it can quickly capture sulfur dioxide. Compared with ordinary calcium oxide, it significantly shortens the reaction time and improves the desulfurization efficiency, reducing the operating costs of equipment.
It reacts vigorously and rapidly with water, releasing a large amount of heat in a short time. It shows outstanding performance in processes that require rapid heating or the provision of an alkaline environment.
It has relatively high purity with low impurity content, which can reduce the adverse effects of impurities on subsequent reactions or product quality. In chemical synthesis, it can avoid side - reactions caused by impurities and ensure product quality.
In wastewater treatment, it has a strong ability to neutralize acidic wastewater. It can quickly adjust the pH value and efficiently coagulate and precipitate impurities and heavy metal ions in the wastewater, improving the wastewater treatment effect.
In the metallurgical industry, it has a good fluxing effect. It can effectively reduce the melting point of slag, promote the separation of slag and metal, and improve the quality and efficiency of metal smelting.
In the rubber and plastic industries, after adding it, the physical properties of products can be significantly improved. For example, it can enhance the tensile strength of rubber and improve the dimensional stability of plastics.
