Ceramics / Glass
Ceramic materials have been used since the early history of mankind. The first figures were formed from ceramic materials and hardened by baking over 24,000 years ago. Other discoveries prove the manufacture of bricks (approx. 14,000 years ago) or the production of practical ceramic vessels (7,000 to 8,000 years ago).
To this day, ceramics have proven their worth in a multitude of applications. Continuous development means that ceramics are also of interest for new applications which require strength, wear resistance, corrosion resistance and temperature stability – and, at the same time, a low specific densitydensity
The density refers to the mass-to-volume ratio of a body..

Ceramic materials are components of plants for metallurgy, chemistry and energy production. Due to their great strength and wear resistance they are used as metal-working tools. The automotive industry uses them, for example, as sparkplug insulators, rocker arm coatings, port liners in the hot area of the exhaust manifold and lightweight valves in the motor. Their electrically insulating, magnetic, dielectric, semiconducting, superconducting properties are used for the production of functional ceramics in the electrical industry.
The mechanical and physical characteristics of ceramic materials can be manipulated by, among other things, selective adjustment of the microstructure.
Additional Information and Machine Recommendations can be found on the following pages:
High mechanical strength values for technical ceramics can only be achieved with the finest microstructures with no impurities or defects. For processing the finest particles in the micron and even the nanometer range with minimal contamination, machines are available for both wet processing and dry grindinggrinding
Crushing of a solid either in dry or suspended form..
Technical Ceramics
With high fineness requirements (< 50 µm) or specific quality criteria, e.g. narrow grain size spectrum, the traditional drum millmill
A mill is a machine with which a feed material is crushed into a finer end product. is often at its limit, both economically and technically. NETZSCH-Feinmahltechnik offers systems and agitator bead mills that can complement or replace the drum mills.
Many decorative paints and glazes are used to refine the surface of ceramic products such as earthenware, stoneware and porcelain. In addition to frits, the basic components of the paints and glazes are primarily special pigments.
Ferrites, which can be classified as soft and hard ferrites, are oxide ceramic materials with the general composition MIIO•Fe2O3, which contain permanent magnetic dipoles. The special magnetic properties are due to the spontaneous parallel or inverse parallel position of the magnetic moments of the atoms in larger areas.
