Product Description:
Calcium oxide, commonly known as quicklime, is a white, caustic, and crystalline solid. It has a high melting point, around 2572°C, which makes it extremely stable under high - temperature conditions. When it comes in contact with water, it reacts vigorously, producing calcium hydroxide and releasing a significant amount of heat. This exothermic reaction is exploited in many applications. In the construction industry, it is used to make mortar. When combined with sand and water, the resulting mixture hardens over time, providing strong bonding for building materials. In the steel industry, calcium oxide is used as a flux in the blast furnace. It helps to remove impurities such as sulfur and phosphorus from the molten iron, improving the quality of the steel. In agriculture, it can be used to amend acidic soils. By raising the soil pH, it makes the soil more suitable for plant growth. In the environmental field, it is used in water treatment to adjust the pH of acidic wastewater and also to remove heavy metals through precipitation. In the chemical industry, it serves as a raw material for manufacturing various calcium - based chemicals. However, handling calcium oxide requires great care. It can cause severe burns to the skin and eyes due to its caustic nature. It should be stored in a dry, well - ventilated area away from moisture sources to prevent premature reaction with water.

 

Application: 

Calcium oxide has multiple applications. In construction, it's used to make mortar for strong building material bonding. In the steel industry, it functions as a flux to remove impurities from molten iron. In agriculture, it amends acidic soils by raising the pH for better plant growth. In environmental water treatment, it adjusts wastewater pH and removes heavy metals. In the chemical industry, it serves as a raw material for calcium - based chemicals. Caution is needed when handling it, as it's caustic and can cause burns; store it dry and away from moisture.
