Therefore, the substance zirconia aluminosilicate refractory ceramic fibres (SiO 2, Al 2 O 3, ZrO 2) as described in this document are a subset of the group of substances which are defined by the refractory ceramic fibres in Annex VI of the Regulation (EC) No 1272/2008.
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6) , or CI 77891. Generally it is sourced from ilmenite, rutile and anatase.itanium dioxide occurs in nature as the well-known minerals rutile, anatase and brookite, and additionally as two high pressure forms, a monoclinic baddeleyite-like form and an orthorhombic Î±-PbO2 -like form, both found recently at the Ries crater in Bavaria. It is mainly sourced from ilmenite ore.
