25、Classification of dense shaped refractory products Part 4: Special products1 ScopeThis part of ISO 10081 specifies the classification and designation of dense shaped refractory products of special composition includinga) oxide products,b) oxide and non-oxide products,c) non-oxide silicon carbide or
26、carbon-based products, andd) further special products which are only designated but not classified, for example, non-oxide products, such as boride, nitride or further combinations of the series listed above.2 PrincipleDense shaped special products shall be classified according to the following six
27、criteria:a) the type of product;b) the group determined by the content of its main chemical component(s);c) the principal raw material(s);d) the state of the raw materials;e) the nature of the bond;f) any post-treatment.3 Classification3.1 Type of productThe following types of dense shaped refractor
28、y special products shall be classified by chemical analysis as shown in 3.2.a) alumina-chromia (ACr);b) chromia (Cr);c) alumina-chromia-zirconia (ACrZ);d) alumina-chromia-zirconia-silica (ACrZS);e) zirconia-silica (ZS);f) alumina-zirconia-silica (AZS);g) alumina-carbon (AC); ISO 2014 All rights rese
