What is BaTiO3 SC?
BaTiO3 SC is BaTiO3 supplied in the SC condition — use for photorefractive optics, domain-engineering research and reference dielectric/piezo measurements; expensive and small sizes only. BaTiO3 SC has a tensile strength of 55 MPa (7.98 ksi), weaker than 65% of ceramic grades. Elongation at break is 0% and the elastic modulus is 125 GPa (18.1 Msi). BaTiO3 SC has a density of 6.02 g/cm³ (0.217 lb/in³), heavier than 65% of ceramic grades. It melts at 1,625°C (2,957 °F). SINT is the default condition FabDigit quotes; SC is available on request or by drawing note.
Advantages
- Low embodied carbon — 5 kg CO₂/kg, better than 76% of ceramic grades
Limitations
- Low fracture toughness — 0.5 MPa·√m (0.455 ksi·√in), worse than 100% of ceramic grades

Working with BaTiO3 SC
Is BaTiO3 easy to machine?
Green or bisque machining is the practical route; fired bodies require diamond grinding, dicing and lapping with care for chipping.
Can BaTiO3 be welded?
Not weldable — joined by metallization (Ag, Ni/Cu, Ag-Pd) plus soldering, or by active-metal/glass brazing.
Can BaTiO3 be formed, bent or molded?
Formed as tape-cast layers, uniaxial/isostatic pressed discs or extruded shapes, then sintered 1250–1400 °C (lower with Cu-compatible reducing atmospheres and sintering aids).
What surface finishes work on BaTiO3?
Fired surfaces are lapped/polished for electrode adhesion; termination by screen-printed silver, sputtered Ni/Cr or electroless Ni plating.
BaTiO3 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.

BaTiO3 SC — frequently asked
What is BaTiO3 SC used for?
BaTiO3 SC is typically used for MLCC capacitor dielectrics, PTC thermistors, piezoelectric transducers and PTC heaters. In short: highest-permittivity capacitor dielectric; ferroelectric perovskite base material; PTC resistance switching.
What is the tensile strength of BaTiO3 SC?
BaTiO3 SC has a typical tensile strength of 55 MPa (7.98 ksi) — weaker than 65% of ceramic grades. Strength varies by condition: see the 3 listed tempers.
