Yttrium Oxide Transparent Ceramic Cover for UV/IR & High-Temperature Viewports

Yttrium Oxide Transparent Ceramic Cover Applications

• UV/IR Equipment (curing lamps, IR emitters)

  ✅Key Advantages

  1. Thermal-throughput balance — Stable transmission with thickness tuned for lamp output.
  2. Clean sealing — Controlled flatness/edge finish for O-ring interfaces, reducing leaks.
  3. Service life in cycling — Geometry and finish reduce chipping during maintenance.

  ✅ Problem Solved

  A curing-system OEM standardized on Ø75×3 mm covers with DS-polish and R0.5 edge; field returns for chipped covers dropped from ~6%到~1.2% over 12 months, and maintenance time per lamp change fell ~25% due to quicker seating and fewer re-alignments.

• Furnace Viewports/High-Temperature Inspection Ports

  ✅Key Advantages

  1. Temperature headroom — Cover remains dimensionally stable for routine checks.
  2. Contamination control — Polished side inward reduces deposit adhesion.
  3. Fit-for-frame — CTE and thickness tolerances matched to metal adapters.

  ✅ Problem Solved

  A heat-treat facility adopted 100×100×4 mm covers with AR-inside; window replacement interval extended from ~3 to ~6 months, while unplanned downtime linked to viewport failure decreased by ~40% across two lines.

• Process Analyzers & Inline Sensors

  ✅Key Advantages

  1. Defined band response — Coating and thickness match detector bandpass.
  2. Signal consistency — Tight parallelism stabilizes path length and spot focus.
  3. Traceable batches — Laser IDs support calibration tracking.

  ✅ Problem Solved

  A gas-analysis module vendor specified Ø50×2 mm covers with ≤0.05 mm parallelism; sensor gain recalibration frequency dropped ~30%, improving factory test throughput and lowering warranty returns over two quarters.

 Y₂O₃ Transparent Ceramic Cover Usage Instructions

• Installation

  1. Inspect the product before use
  Open the pouch in a clean area, using lint-free gloves. Check for chips, edge cracks, or coating scratches under diffused light.
  2. Handle carefully during placement
  Avoid any metal-to-edge contact; hold by the rim, not the optical surface. Use a soft, non-metallic fixture when inserting into the housing.
  3. Mounting orientation
  Always install the cover with the polished or AR-coated side facing the specified process side as indicated on the drawing or engraved mark.
  4. Apply uniform torque
  Tighten screws in a cross-diagonal sequence with a torque-limited tool. Uneven compression may lead to micro-cracks or optical distortion.
  5. Seal verification
  Confirm gasket or O-ring compression using feeler gauges or calibrated torque; ensure no trapped air bubbles at the interface.
  6. Record traceability
  Log the part ID, orientation, torque value, and assembly date in maintenance records to track future replacements.

• Use

  1. Temperature ramping
  Follow the tool’s thermal ramp program. Increase temperature gradually (≤5 °C/min typical) to minimize thermal stress on the ceramic cover.
  2. Avoid direct cold airflow
  Do not expose a hot cover to sudden air or gas jets; thermal gradients above 50 °C/min can cause micro-fractures.
  3. Condensate prevention
  Keep the surface dry and clean. If condensates are unavoidable in the process, specify an anti-soiling or hydrophobic coating during procurement.
  4. Environmental compatibility
  For corrosive or plasma environments, ensure the sealing materials (metal frame, O-ring) are chemically compatible with Y₂O₃.
  5. Regular inspection
  Check for surface haze or deposits after 200–300 hours of operation; clean or replace if optical transmission decreases by more than 5%.

• Storage

  1. Original packaging
  Store the product in its foam cavity and clean pouch to prevent micro-scratches and particle contamination.
  2. Humidity and temperature
  Keep relative humidity below 60% RH and temperature between 10–30 °C. Avoid rapid temperature changes to prevent condensation.
  3. Segregation and labeling
  Separate by thickness and diameter; label storage trays clearly to prevent mismatched installation.
  4. Long-term storage
  For storage over six months, inspect surface condition and re-clean before installation; recheck coating adhesion if applicable.

• Cleaning

  1. Routine cleaning
  Use lint-free microfiber cloths and neutral solvents such as isopropanol or ethanol. Blow off dust with dry, filtered nitrogen before wiping.
  2. Coated surface care
  Avoid circular wiping motion. Instead, gently drag the cloth in one direction with minimal pressure. For AR-coated sides, use only coating-safe solutions.
  3. Stubborn contamination
  For baked-on residue, apply solvent-soaked lint-free wipes for 1–2 minutes before gently removing. Do not use ultrasonic cleaning unless validated by ADCERAX engineering.
  4. Handling after cleaning
  Air-dry in a clean, particle-free area. Avoid touching the optical area even through gloves; store immediately in a clean pouch.

Yttrium Oxide Transparent Ceramic Cover FAQ

1. Q: What temperature can a Y₂O₃ transparent cover withstand?
   A: Yttrium Oxide Transparent Ceramic Covers remain structurally and optically stable up to 1000–1200 °C under non-load conditions, far exceeding the limits of quartz or glass windows.
2. Q: How does a Yttrium Oxide cover compare to sapphire or spinel windows?
   A: Unlike sapphire (Al₂O₃) or spinel (MgAl₂O₄), Y₂O₃ offers lower infrared emissivity (<0.03 @ 3–5 µm) and broader transmission (0.25–8 µm), making it superior for mid-IR or thermal imaging applications where accurate radiation transfer is essential.
3. Q: What is the typical optical transmission of Yttrium Oxide transparent ceramics?
   A: A double-sided polished Y₂O₃ cover can achieve 80–81% theoretical transmission between 0.25 µm – 8 µm, depending on thickness, surface roughness, and coating.
4. Q: Can Y₂O₃ transparent covers be AR-coated or surface-treated?
   A: Yes. ADCERAX offers single- or double-side AR coatings optimized for UV, visible, NIR, or MWIR bands. Functional coatings such as anti-soiling, hydrophobic, or hard-coat layers can also be applied to reduce cleaning frequency.
5. Q: What are the available sizes and tolerances for Yttrium Oxide Transparent Covers?
   A: Standard round covers range from Ø10 mm – Ø200 mm and thicknesses of 1–8 mm, with machining tolerances typically ±0.05 – 0.20 mm for diameter or thickness. Custom geometries and bolt patterns can be machined on request.
