About Sea Water Magnesia

Seawater magnesia, also known as magnesium oxide (MgO), is a valuable industrial material produced from seawater or brine. Seawater magnesia is widely used in refractory applications, such as furnace linings, due to its high melting point and resistance to thermal shock. It also finds use in the production of cement, fertilisers, and as a source of magnesium in various chemical processes. Seawater magnesia is being produced since the early 20th century. In the 1930s, the development of the Pidgeon process, which uses ferrosilicon to reduce magnesium oxide, led to increased production. Today, seawater and brine are the primary sources of magnesium, with seawater magnesia accounting for a significant portion of global magnesium oxide production.

Properties of Sea Water Magnesia

Seawater magnesia, or magnesium oxide (MgO), is a white, crystalline solid with a high melting point of 2,852°C. It has a molar mass of 40.30 g/mol and a density of 3.58 g/cm cube. Seawater magnesia has high thermal and chemical stability, making it resistant to acids, bases, and high temperatures. It exhibits a high refractory index, low thermal conductivity, and good electrical insulation properties. Chemically, seawater magnesia is an alkaline earth metal oxide that readily reacts with water to form magnesium hydroxide (Mg(OH)2). Its unique properties make it suitable for various applications, such as refractory materials, cement production, and as a source of magnesium in chemical processes.

Manufacturing Process of Sea Water Magnesia

The production of seawater magnesia (magnesium oxide) begins with the collection of seawater or brine containing dissolved magnesium ions, which is then concentrated through solar evaporation in ponds to increase the magnesium ion concentration. Impurities like calcium and potassium are removed through chemical treatment and settling, followed by the precipitation of magnesium hydroxide by adding lime (calcium  hydroxide). The magnesium hydroxide slurry is filtered, and the collected solid is calcined in a kiln to convert it into magnesium oxide (MgO). The calcined magnesia is cooled, ground into a fine powder, and sized according to application requirements. After undergoing quality control tests, the final product is packaged and distributed to various industries, including refractories and agriculture, effectively using seawater as a sustainable source of magnesium.

Synthesis of Seawater Magnesia

Seawater magnesia, also known as magnesium oxide (MgO), is produced by extracting magnesium from seawater. The process involves several stages, such as:

1. Precipitation

The first step in producing seawater magnesia is the precipitation of magnesium hydroxide (Mg(OH)2) from seawater. This is achieved by adding lime (CaO) to the seawater. The chemical reaction is as follows:

Mg 2+ (aq) + CaO (s) + H2O (l) → Mg(OH)2 (s) + Ca 2+ (aq)

In this reaction, magnesium ions (Mg 2+) in the seawater react with lime, which dissolves in water to form calcium hydroxide (Ca(OH)2). This calcium hydroxide then reacts with the magnesium ions to precipitate magnesium hydroxide (Mg(OH)2) as a solid.

2. Filtration

After precipitation, the magnesium hydroxide is separated from the seawater through filtration. The solid Mg(OH)2 is collected, and the remaining liquid is discarded or further processed for other purposes.

3. Calcination

The filtered magnesium hydroxide is then subjected to calcination, a process in which it is heated at high temperatures (around 1000-1100°C) to produce magnesium oxide (MgO). The chemical reaction involved is:

Mg(OH)2 (s) → MgO (s) + H2O (g)

In this reaction, magnesium hydroxide decomposes into magnesium oxide and water vapor. The water vapor is driven off, leaving behind pure MgO.

4. Cooling and Storage

After calcination, the magnesium oxide is cooled and then stored or packaged for distribution. The final product, MgO, is a fine white powder that is used in various industrial applications.

Applications and Drivers of Sea Water Magnesia

The seawater magnesia market is driven by its diverse applications across refractories, agriculture, chemicals, and construction industries. In the refractory industry, seawater magnesia is essential for manufacturing high-performance bricks and linings that withstand extreme temperatures, particularly in steel production. In agriculture, it serves as a soil amendment to enhance fertility and crop yields. Additionally, seawater magnesia is used in water treatment processes to remove impurities and as a cement additive to improve concrete durability. The increasing demand for these applications, coupled with growing infrastructure development, significantly fuels the market's growth.
