Anhydrous Borax

Description:
Anhydrous borax, also known as sodium borate or borax, is a white, crystalline solid that is primarily composed of sodium, boron, oxygen, and hydrogen. Its chemical formula is Na2B4O7, and it is characterized by its high solubility in water, making it useful in various applications. Anhydrous borax is hygroscopic, meaning it can absorb moisture from the environment, which can affect its stability and handling. It exhibits alkaline properties, with a pH typically above 7 when dissolved in water. This compound is commonly used in glass and ceramics manufacturing, as a flux in metallurgy, and as a cleaning agent due to its ability to soften water. Additionally, it has applications in agriculture as a micronutrient for plants and in various industrial processes. Safety considerations include avoiding inhalation and skin contact, as it can be irritating. Overall, anhydrous borax is a versatile chemical with significant industrial and household applications.

  • Sodium tetraborate anhydrous, particle size <16 mesh

    CAS:
    <p>Boron is a metal that has been used as a preservative, fire retardant, and insecticide. It has also been used for the treatment of wastewater and in analytical methods such as an experimental solubility data. Sodium tetraborate anhydrous is a white powder that is soluble in water. It has been shown to be toxic to some organisms, including humans, and may cause irritation. Tetraborates are also used in the treatment of wastewater because they reduce the amount of phosphorus pentoxide needed and decrease the toxicity of copper chloride. The optimum concentration for boron-containing compounds is 0.3%.</p>
