The starch is mixed with steam or catalytically active acid under increased temperature and pressure. This converts the otherwise insoluble starch into awater soluble product, which mainly asbinderapplies. A commonly known use is thisWet adhesive coating (also called gumming) of postage stamps and kraft paper tapes. However, it is also used as a food additive or as a binding agent in pharmaceuticals.

Boron carbide (also known as black diamond) is, like our silicon carbide and silicon nitride, an exceptionally hard and therefore wear-resistant material. This has made it the material of choice for nozzle materials, baffle plates (jet mills), ballistic protection elements, cutting tools, and grinding, polishing, or lapping powders. More recent applications have emerged in foundry technology (cost-effective supply of boron), rocket fuels, and semiconductor technology. We supply common fractions.

This very pure amorphous boron powder has a very small particle size. Compared to aluminium it theoretically has a much greater energy content, which can be advantageous in appropriate applications (energetic materials). However, since boron is always covered with a layer of boron trioxide , albeit an extremely thin one, the use of magnesium fluoride should be considered. Boron is extremely reactive and reacts very quickly with metals with the exothermic formation of metal borides. However, it is stable in open air.Amorphous boron is primarily used in the following areas:Glass and ceramics Pyrotechnics Gas generators Aerospace technology (ignition device Actuators)Semiconductors Metallurgy Carbide tools Radiation absorbers Signal word: ATTENTION!
