min. 98.0% barium oxalate, pure, powder, C2BaO4, CAS No.: 516-02-9

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!

Didymium Today, however, the term is no longer used because the rare earths have been identified and divided into individual elements. Didymium was first discovered in 1841 by the Swedish chemist Carl Gustaf Mosander. He isolated it from cerite, a mineral that is a mixture of rare earths. However, it later turned out that Didymium itself is a mixture of the elements Praseodymium and neodymium. Didymium with its essential components Praseodymium and Neodymium finds a wide range of applications in glass technology and electronics. For example, they are used for the production of Permanent magnets, Lasers / optical fibers, Glasses (special glasses for glassblowers - yellow filters) and Ceramics (glazes) used. It is also occasionally used as a catalyst in pyrotechnics and rocket technology.At high temperatures, the mixed oxalate decomposes into the corresponding oxides. This means that the didymium can easily be further processed in other fields of application.  Signal word: ATTENTION! Hazard warningsH302: Harmful if swallowed. H315: Causes skin irritation.

Lithium carbonate is used, among other things, in glass production, in the ceramics industry and in metallurgy used. It is used as a melting flux and to increase the melting points of glasses and ceramics. In metallurgy, lithium carbonate is used to produce lithium metal and lithium compounds (lithium hydroxide, also with us available) used.  Chemical/physical analysis values (typical) Appearance: White, very dusty powder insoluble. in / insol. in HCL [%]: 0.0001 Ca[%]: 0.01 Cl [%]: 0.01 SO4 [%]: 0.01 H2O [%]: 0.24 Na [%]: 0.05 K [%]: 0.004 Signal word: Attention!
