Our Materials

Five Advanced Ceramic Systems, One Manufacturing Platform

Every material is formulated, pressed, sintered and precision-machined in-house — so tolerances, purity and delivery are under our control from start to finish.

High-purity alumina ceramic components

Alumina (Al₂O₃)

High-purity 99% / 99.5% / 99.7% / 99.8% grades with outstanding electrical insulation, wear and plasma resistance — the workhorse of semiconductor process chambers.

Key Industry Focus

Engineered for Semiconductor Equipment

A large share of our output serves semiconductor manufacturing equipment, where purity, plasma resistance and dimensional stability directly determine wafer yield.

  • Wafer handling — end effectors, vacuum chucks and robotic arm components
  • Etch & CVD/PVD chambers — liners, showerhead supports, focus rings, insulators
  • Electrostatic chuck (ESC) and heater core parts in AlN and Al₂O₃
  • CMP and wafer-carrier components in high-purity SiC
  • Cleanroom-compatible packaging and full material traceability

Frequently Asked Questions

Answers for Buyers and Engineers

What is Dolphin Advanced Ceramic and where is it located?

Dolphin Advanced Ceramic is an advanced technical ceramics manufacturer and industrial ceramics research institute based in Zibo City, Shandong Province, China. Powder synthesis, pressing, high-temperature sintering, diamond grinding and metallization all happen in-house, and we supply high-purity alumina, aluminum nitride, zirconia and silicon carbide components to industrial customers worldwide.

Which industries do you mainly supply?

Our largest customer group is semiconductor manufacturing equipment — wafer handling, etch and CVD/PVD chambers, electrostatic chucks and CMP. We also serve the LED and optoelectronics, photovoltaic and new-energy, medical and dental, automotive and EV, and general industrial wear and fluid-handling industries.

What purity grades of alumina ceramic can you produce?

Four high-purity grades: 99%, 99.5%, 99.7% and 99.8% Al₂O₃, with bulk densities of 3.82–3.95 g/cm³ and flexural strength of 340–420 MPa. The 99.7% and 99.8% grades are specified where wafer-exposed surfaces must minimise particle generation and ionic contamination.

What is the difference between alumina, aluminum nitride, zirconia and silicon carbide?

Alumina gives the best cost-to-performance balance for insulation, plasma resistance and wear. Aluminum nitride reaches thermal conductivity up to 200 W/m·K while staying electrically insulating — the choice for power-module substrates and heat spreaders. Zirconia (Y-TZP) has the highest fracture toughness of the four, used for cutting blades, pump parts, precision balls and medical components. Silicon carbide offers the best high-temperature strength, thermal-shock and plasma resistance, used for focus rings, wafer carriers and mechanical seals.

Can you manufacture ceramic components to our drawings?

Yes — custom manufacturing is our core business. Send a 2D drawing, 3D model or sample with the material grade, quantity and tolerance or surface-finish requirements. Our engineers return a manufacturability review and quotation within 24 hours, and we diamond-grind to ±0.005 mm with finish down to Ra 0.4 µm.

How do you ship internationally and what are your lead times?

We ship worldwide from Zibo, Shandong, China by air or sea freight with export documentation handled in-house. Standard parts usually ship in 2–4 weeks; custom tooling and precision-machined parts typically take 4–8 weeks depending on complexity and quantity. Cleanroom-compatible packaging and full material traceability reports are available on request.
