What Are High-Purity Inorganic Chemicals?

High-purity inorganic chemicals are specialized compounds that have undergone rigorous purification processes, often achieving purity levels of 99.9% (3N) or even higher. These compounds, which include a variety of elements and molecules, exclude organic hydrocarbons and their derivatives. Some of the most sought-after inorganic chemicals are rare earth oxides, which have unique properties essential for various technological applications. Inorganic chemicals are indispensable in modern science and industry.

What Applications Are High-Purity Inorganic Chemicals Used for?

High-purity inorganic chemicals are fundamental to a range of advanced applications. They play a crucial role in the development of optical materials, photonics, technical ceramics and glass. With the inclusion of rare earth oxides, inorganic chemicals are vital in electronics and sustainable energy solutions. Their precision and reliability make them essential to both research and industrial sectors.

Our Selection of Inorganic Compounds for Sale

MSE Supplies offers a broad selection of inorganic compounds to support various needs. While our inventory is extensive, highlights of our chemicals include:

  • Alumina powder: Alumina is a ceramic used for various industrial applications, such as abrasives, filling materials, catalysts, construction materials and more. This compound is also known for its wear and corrosion resistance, making it ideal for protective coatings. The alumina powder's qualities vary by particle size.
  • Silicon: Silicon is a highly versatile element and has uses in construction materials, transistors, solar cells, computer chips and other devices. This element is an important part of ceramics and bricks and is essential for ferrosilicon in the steel industry. Silicon has many polymers that are also major players in various sectors, such as silica, silicides and silanes.
  • Titanium dioxide: When titanium naturally interacts with oxygen, it creates titanium dioxide. This fine, white powder is most commonly used for its pigmentation abilities. It can also be produced as a nanomaterial for improved transparency and UV light absorption. Titanium dioxide is often used in paints, plastics, rubber, coatings, adhesives, paper and many other industrial and consumer products.
  • Lanthanum: Lanthanum is a highly reactive rare earth element that quickly dissolves in diluted acids and slowly reacts with water. It also interacts with air at room temperature to create La2O3. Some of the most common applications for this element are lighting-related, such as fluorescent tubes, televisions and energy-saving lamps. In optics, lanthanum is used for lenses and glasses that absorb radiation.
  • Ethylene carbonate: Ethylene carbonate is most commonly used for electrolyte solutions in lithium batteries. It's a highly polar solvent with low toxicity and high solubility for polymers. This compound is helpful for meeting high quality standards as it has naturally low impurity. Other applications for ethylene carbonate include lubricants, capacitor electrolytes, organic solvents and fiber processing agents.
  • Yttrium oxide: Yttrium oxide or Yttria is a rare earth oxide often used in optic, glass and ceramic applications. This element commonly acts as a stabilizer in ceramic compositions. It's known for its plasma resistance, heat resistance, high stability and usefulness in high-temperature applications. 
  • Samarium oxide: Samarium oxide has a high neutron absorption capacity and is insoluble in water. Common applications for this compound are optical glass and infrared-absorbing materials. In nuclear power reactors, it is used as a neutron absorber in control rods. This compound has also been used in lasers to create intense light beams for metal burning.
