of these products is precision ceramic processing, which ensures superior performance, reliability, and longevity.
1. Customized Zirconia Ball Milling Jars
Description:
These are grinding containers used in ball mills, designed for size
reduction, dispersing, and mixing of materials. Customization is a
key feature, allowing them to be tailored to specific application
needs far beyond standard offerings.
Key Features & Specifications:
- Material: Made from Yttria-Stabilized Zirconia (YSZ), typically with 3mol% or 5mol% Yttria. This provides exceptional
wear resistance and prevents contamination of the milled material.
- High Wear Resistance: Zirconia's incredible hardness (Vickers
hardness > 1200) ensures the jar lasts significantly longer than
other materials like alumina, stainless steel, or PTFE, reducing
downtime and replacement costs.
- Contamination-Free Milling: Zirconia is chemically inert and
non-magnetic. It will not react with or introduce impurities into
the sample, which is critical for R&D, pharmaceuticals, and
electronics material production.
- High Density & Strength: The fine-grained, high-density structure
minimizes porosity, leading to a smoother inner surface that is
easier to clean and less likely to trap particles.
Customization Options:
- Size & Volume: From small 50ml jars for lab research to large 10L+
jars for production.
- Geometry: Standard cylindrical, tapered, or unique shapes as
required.
- Lid Design: Custom ports for inert gas, vacuum, or temperature
monitoring. Various sealing mechanisms (e.g., O-ring, clamp-on).
- Internal/External Finishing: Polished to a mirror finish for easy
cleaning or a specific roughness.
Applications:
- Pharmaceutical R&D and production.
- Battery material synthesis (e.g., cathode & anode powders).
- Electronics ceramics (dielectrics, ferrites).
- Pigment and dye dispersion.
- Geology and mineral sample preparation.
2. High-Temperature Resistant Zirconia Structural Ceramic Parts
Description:
These are engineered components designed to perform in demanding
mechanical and thermal environments where metals or plastics fail.
They are not just materials, but fully finished, ready-to-install
precision parts.
Key Features & Specifications:
- Exceptional High-Temperature Resistance: Zirconia parts can operate
continuously at temperatures up to 1,400°C - 1,600°C (depending on the stabilizer), maintaining their structural
integrity.
- Remarkable Fracture Toughness: Zirconia has the highest toughness
of all advanced ceramics due to a mechanism called "transformation
toughening," making it highly resistant to chipping, cracking, and
thermal shock.
- Excellent Mechanical Properties:
- High Strength: Bending strength can exceed 1,000 MPa.
- Low Thermal Conductivity: Acts as an excellent thermal insulator.
- Wear & Corrosion Resistance: Impervious to most acids, alkalis, and
molten metals.
Common Part Types:
- Insulation Components: Thermocouple sleeves, furnace liners,
heating element holders.
- Wear Parts: Nozzles for sandblasting or spray drying, guides,
rollers, bearings, and cutting tools.
- Fixturing & Setter Plates: Used in sintering furnaces for
electronics (e.g., MLCCs) due to their chemical inertness and
stability.
Applications:
- Aerospace (thermal barrier coatings, engine components).
- Semiconductor manufacturing (wafer processing fixtures).
- Heat treatment and metallurgical industries.
- Automotive (sensors, wear-resistant inserts).
- Medical and dental implants and instruments.
3. The Core: Precision Ceramic Processing
This is the technological backbone that enables the production of
high-quality zirconia parts. It involves a multi-step, tightly
controlled manufacturing process.
Detailed Process Flow:
Powder Preparation & Formulation:
- Using high-purity, sub-micron zirconia powder with precise yttria
stabilizer ratios.
- Custom additives (sintering aids, pigments) can be incorporated.
Forming / Shaping:
- Uniaxial / Isostatic Pressing: For simple, solid shapes like
blocks, rods, and simple plates. High volume production.
- Injection Molding: For complex, near-net-shape parts with high
dimensional repeatability. Ideal for mass production.
- Tape Casting: For producing thin, flat sheets used in electronics.
- Extrusion: For creating long products with a consistent
cross-section (e.g., tubes, rods).
Machining in the "Green" or "Bisque" State:
- After forming, the part is in a soft, chalk-like state ("green") or
a partially sintered, porous state ("bisque").
- CNC machining is performed at this stage to achieve intricate
geometries, tight tolerances, and specific surface finishes that
are impossible to achieve with pressing/molding alone. This is a
key aspect of "customization."
Sintering:
- The core process where the shaped part is fired in a
high-temperature kiln (typically >1,500°C).
- The particles fuse together, causing the part to shrink
significantly (20-25%) and densify into a solid, polycrystalline
ceramic with its final mechanical properties.
Precision Finishing & Hard Machining:
- After sintering, the part is extremely hard. Any further machining
requires diamond-impregnated tools.
- Processes like diamond grinding, lapping, and polishing are used to achieve ultra-precise final dimensions (tolerances
within ±0.001"), specific surface roughness (Ra < 0.1 µm), and
sharp edges.
