Analysis of minerals - Import export

We offer you the classification of 'old mineral wool' or such mineral fibres without RAL quality mark regarding their carcinogenic risk potential The carcinogenicity index, KI, is a dimensionless quantity and is determined according to the material composition of the mineral fibres to be evaluated. According to IFA / BIA method 7488, it is calculated from the sum of the mass contents (in MA-%) of Na2O, K2O, CaO, MgO, BaO and B2O3 minus twice the mass content of Al2O3. Vitreous mineral fibres are classified according to the KI according to TRGS 905 as follows, if their dimensions correspond to the WHO - fibre - definition: (length > 5µm, diameter < 3 µm, ratio length : diameter > 3 : 1) Glassy WHO fibres with a carcinogenicity index KI <= 30 are classified in category 1B. WHO vitreous fibres with a carcinogenicity index KI > 30 and KI < 40 are classified in category 2. WHO vitreous fibres shall not be classified as carcinogenic if their carcinogenicity index KI >= 40.

Ceramic crucible is the use of high purity powder, trace elements added, from the phase structure and microstructure of modified production.A smelting vessel. Products are aluminum oxide crucible and fully stabilized zirconia porous crucible, the former is mainly used for smelting and laboratory Firing other high melting point material, which is mainly used for the melting temperature with Pt,Rh, Au and other precious metal.
