What is BS EN 725-11 - Ceramic powders - Determination of densification on natural sintering about?
BS EN 725-11 is the European standard on advanced technical ceramics that covers the determination of densification properties of ceramic powders on natural sintering. BS EN 725-11 describes a method for determining the densification of ceramic powders on natural sintering, without the application of any external pressure.
BS EN 725-11 is applicable to pure oxides, mixtures of oxides and solid solutions. Inorganic sintering additives may be used where their presence is reported.
Who is BS EN 725-11 - Ceramic powders - Determination of densification on natural sintering for?
BS EN 725-11 on ceramic powders - determination of densification on natural sintering is useful for:
- Advanced technical ceramics manufacturers
- Ceramic powders manufacturers
- Mechanical engineers
Why should you use BS EN 725-11 - Ceramic powders - Determination of densification on natural sintering?
Densification is the act of reducing porosity in a sample, thereby making it denser. Grain growth is the process of grain boundary motion and Ostwald ripening to increase the average grain size. When ceramic powder compacts are heat-treated at high temperatures, they shrink and are densified due to sintering.
Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials.
BS EN 725-11 on the densification properties of ceramic powders specifies the test method to determine the extent to which ceramic powder compacts made of granulated or ungranulated ceramic powders are densified using sintering.
BS EN 725-11 can help you produce complex shapes without secondary machining operations and can be used for the shaping of materials with a high melting point.
