Production & properties
Porcelain is a silicate-ceramic material based on natural raw material.
The chemical components are 30 – 75 % SiO2 and 20 – 65 % Al2O3.
The glass phase is 60 – 70 %. Crystalline components are embedded in this.
Porcelain is divided into different groups, depending on the moulding technique:
- C 110, quartz-enriched porcelain: slip-cast and extruded
- C 111, pressed porcelain: cost-effective production of complicated moulded parts in large quantities through dry and wet pressing
Technical porcelain is an excellent insulation material for electrical engineering (high and low voltage), is dielectric – even under the influence of humidity – tracking-resistant, non-combustible and absolutely heat resistant up to 1000 °C.
Thread guides for textile machines made of pore-free glazed hard porcelain guide modern carbon-, kevlar- and aramid fibres especially reliably.
Its chemical stability makes porcelain an indispensable material in chemical plant construction.
Products that are produced in large quanitities include lamp sockets.
