BS EN 725-2:2007

What is BS EN 725-2 - Determining impurities in barium titanate powders about?

BS EN 725 is a European standard on advanced technical ceramics that discusses the methods of test for ceramic powders.

BS EN 725-2 is the second part of a multi-part series that describes a method for the determination of impurities in barium titanate powders using inductively coupled plasma optical emission spectroscopy (ICP-OES).

The method under BS EN 725-2 applies only to stoichiometric barium titanate. The maximum concentrations measured for each impurity are as follows:

• Sr 4 mg/g (4 000 ppm)
• Ca 500 μg/g (500 ppm)
• K 200 μg/g (200 ppm)
• Na, Mg, Al, Fe, Nb 100 μg/g (100 ppm)

The minimum concentration or detection limits are from 1 μg/g to 5 μg/g (1 ppm to 5 ppm) under BS EN 725-2.

Who is BS EN 725-2 - Determining impurities in barium titanate powders for?

BS EN 725-2 on determining impurities in barium titanate powders is useful for:

• Barium titanate powder manufacturers
• Materials and Mechanical Engineers
• Electrical industry

Why should you use BS EN 725-2 - Determining impurities in barium titanate powders?
