Barium sulfate is an important material in various industries. It is often used as an X-ray contrast agent in medical imaging and also has applications in the oil and gas industry, where it is used in the production of drilling fluids and as filler is used in plastics and rubber. Barium sulfate is also widely used in the paper and paint industry, where it is used as a white pigment, active support of titanium dioxide and to increase the density of paints and varnishes. It is also very frequently used in veterinary medicine . It is important to note that barium sulfate is high density and is not soluble.  Barium sulfate is the only barium salt that is not considered dangerous goods.This barium sulfate is extracted directly from the mineral. For this purpose it is purified, dried and ground several times. This means that the material has a very low and therefore machine-friendly quartz content (reduced wear) and high brightness.

Calcium oxalate is a crystalline solid, which is slightly soluble in water. In addition to its use in pyrotechnics, the material is primarily used in laboratory analysis, ceramics or metal processing. Kidney stones form from calcium oxalate when high concentrations of calcium and oxalic acid are present in the urine. It can also be found in other parts of the body such as the urinary bladder, ureters, and even the lungs.Typical chemical specifications: Formula: CaC2O4 CAS number: 5794-28-5 Purity: min. 99.5% Fe: 10 ppm Cr: 5 ppm Cu: 1 ppm K: 40 ppm Ni: 6 ppm Zn: 40 ppm Volatile components: 0.3%   Signal word: ATTENTION! Danger information H302 + H312 Harmful if swallowed or in contact with skin Safety instructions P264 Wash skin thoroughly after use.

The chemical formula of sodium oxalate is Na2C2O4.This compound is in the form of colorless crystals and is highly soluble in water. Sodium oxalate is mainly used in laboratories and has various applications:Analytical Chemistry: Sodium oxalate is used as an analyte for the determination of calcium and barium ions. With these ions it forms poorly soluble salts that can be used as a detection reaction.Decolorants: Sodium oxalate is used in some decolorants to remove unwanted dyes. It can help eliminate discoloration on textiles, paper or other materials.Cleaning Agents: Because of its ability to complex and remove metal ions, sodium oxalate is used in some cleaning products, particularly for removing rust stains or cleaning metal surfaces.Chemical Reactions: Sodium oxalate can also be used as a reducing agent in some chemical reactions. It reacts with strong oxidizing agents and can itself be oxidized. Signal word: ATTENTION!
