ISO 21813 is an International Standard on fine ceramics that aims to evaluate the chemical properties of a wide range of elements present in high purity barium titanate powders, to determine its performance.
ISO 21813 specifies methods for the chemical analysis of fine high purity barium titanate powders used as the raw material for fine ceramics. Barium and titanium contents, the major elements, are determined by using an acid decomposition-gravimetric method or an acid decomposition-inductively coupled plasma-optical emission spectrometry (ICP-OES) method.
BS ISO 21813 on chemical analysis of high purity barium titanate powders is useful for:
Barium titanate is dielectric compound material considered as the backbone of the electronic ceramic industry; that is voltage-resistant and acts as insulation in various industrial applications. Through the methods of determining levels of barium and titanium, amongst other chemicals, ISO 21813 aids manufacturers in the production of high purity barium titanate powders with specified analytes and ranges. This helps manufacturers of the product and the users of this raw material benefit from its high permittivity and piezoelectric properties.
