Substitution of aluminosilicate ceramic fibres in vitrification furnaces
A manufacturer of accumulators for sanitation of water used vitrification furnaces covered with fireproof ceramic fibres of aluminosilicate. These fibres are carcinogen and workers, by advice of the regional union health and safety department, demanded their substitution. Wollastonite was chosen as an alternative product. Wollastonite is a highly resistant calcium silicate used in coating compounds as an alternative to asbestos and artificial fibres.
