What is Technical Porcelain (C110)?
Technical Porcelain (C110) is a feldspar-based vitrified silicate ceramic used for high-voltage insulators and general technical ceramic components, available unglazed (C110-UG), glazed (C110-GL) and in the related C120 and C130 bodies. Engineers use it for its low cost, dielectric strength and weathering resistance, in slip-cast, extruded, jiggered or dry-pressed forms. Typical values are density 2.4 g/cm³, tensile strength 28 MPa, elastic modulus 70 GPa, thermal conductivity 1.5 W/m·K and service to 900 °C. Mechanical strength, thermal conductivity and temperature capability are low compared with alumina, which is the usual step up when higher strength or 1000 °C-plus service is needed. Technical Porcelain (C110) has a density of 2.4 g/cm³ (0.0867 lb/in³), lighter than 83% of ceramic grades. Technical Porcelain (C110) has a tensile strength of 28 MPa (4.06 ksi), weaker than 82% of ceramic grades. Elongation at break is 0% and the elastic modulus is 70 GPa (10.2 Msi).

Working with Technical Porcelain (C110)
Is Technical Porcelain (C110) easy to machine?
Machine in the green or bisque state (turning, drilling, milling with carbide) and allow ~10–14 % firing shrinkage; fired parts need diamond grinding, lapping or laser/ultrasonic drilling.
Can Technical Porcelain (C110) be welded?
Not weldable — join by glass frit sealing, glaze bonding, ceramic-to-metal cementing (sulphur/Portland cement in insulator caps) or metallized brazing.
Can Technical Porcelain (C110) be formed, bent or molded?
Formed by slip casting, extrusion of plastic body, jiggering or dry/isostatic pressing of spray-dried granulate, then single-fire at ~1200–1350 °C in tunnel kilns.
Technical Porcelain (C110) chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| SiO2quartz + glassy phase | 60 – 72 | 67 |
| Al2O3from clay/kaolin; mullite after firing | 20 – 30 | 25 |

What surface finishes work on Technical Porcelain (C110)?
Silicate glaze (brown/grey/white) sprayed or dipped before firing gives a compressive, self-cleaning surface; unglazed faces are ground flat and edges chamfered to avoid chipping.
