Radium Primary Material.
Manufacturing and processing of high-purity inorganic chemicals.
Synthesis of high purity metal halides
High-quality metal halides as pure substances from our own synthesis, which contain an extremely low level of impurities from oxygen, moisture and foreign metals.
The delivery is possible in various forms, from coarse granules to finely ground powder to spherical particles in various diameters (depending on the material).
The purity level is proven by chemical and spectroscopic analysis in our own laboratory and certified accordingly.
Multi-component mixture of metal halides
Production of mixtures according to given recipes consisting of 2-10 different metal halides.
All production steps are carried out in glove boxes filled with inert gas protecting the product.
Proof of the correct composition and the degree of purity is provided by chemical and spectroscopic analysis in our own laboratory and certified accordingly.
Delivery in different variations according to customer requirements:
Granules
Bullets
in sizes from 100-400µm; packaging units from 20mg - 4g
Press Bodys
in sizes from 1-5mg; packaging units 1-1.000 pieces
More options
it is also possible to combine several mixtures or basic substances in one package.
