Material Integrity & Engineering Science
High-Purity Fused Quartz Crucible Engineering for Demanding Thermal Processes
Serving metallurgical research, high-purity inorganic synthesis, and crystal pulling across the Eastern Mediterranean. Our crucibles are fabricated from natural crystalline quartz sand with purity levels reaching 99.998% SiO₂.
Arc-Fused Multi-Layer Construction
Manufactured using advanced rotational electric arc fusion. Crucibles feature an opaque, micro-bubble-infused outer layer that guarantees exceptional thermal insulation, paired with a completely bubble-free, smooth, vitreous inner layer to prevent melt entrapment and impurity migration.
Thermal Shock & Devitrification Resistance
The extremely low coefficient of thermal expansion (5.5 × 10⁻⁷ /°C from 20°C to 1000°C) ensures that our crucibles endure rapid temperature cycling without spalling or micro-cracking, maintaining structural integrity across prolonged metallurgical runs up to 1450°C.
Strict Chemical Inertness & Trace Control
Virtually inert against severe mineral acids, halogens, and aggressive fluxing compounds (excluding hydrofluoric and hot concentrated phosphoric acid). Trace metallic impurities (Fe ≤ 0.2 ppm, Al ≤ 12 ppm, alkali metals ≤ 0.5 ppm) are kept strictly below analytical thresholds.

Frequently Asked Questions for Paphos Industrial & Lab Buyers
Essential guidance on importing fused quartz crucibles and custom quartz components from China directly into the Republic of Cyprus.
What is the standard production lead time and freight duration to Paphos, Cyprus?
For standard-dimension fused quartz crucibles (e.g., 50 mL – 2000 mL laboratory crucibles, or standard 12"–18" CZ crucibles), production lead times typically range between 7 to 12 working days. Custom geometries or tight-tolerance CNC ground crucibles require approximately 15 to 20 days. For shipping to Cyprus, air express (DHL/FedEx/UPS directly to Paphos) takes 4 to 7 calendar days. Ocean freight shipments arriving at Limassol Port typically require 22 to 28 days sailing time from Qingdao or Shanghai ports.
Can Kavri Quartz manufacture crucibles according to custom CAD drawings or damaged samples?
Yes, over 65% of our production comprises custom OEM/ODM orders. You can provide standard 2D engineering drawings (PDF/DWG), 3D CAD files (STEP/IGES), or photographs with key dimensions (outer diameter, inner diameter, total height, wall thickness, bottom radius, spout design). If you have an obsolete crucible from an imported European or American furnace, you can ship sample fragments or measurements to our engineering facility in Lianyungang, and we will accurately replicate the part.
What are the import duties and customs documentation required for fused quartzware in Cyprus?
In the Republic of Cyprus (an EU member state), fused silica and quartz items generally classify under TARIC / HS Code 7017.10.00.00 (Laboratory, hygienic or pharmaceutical glassware, of fused quartz or other fused silica). Import duty for fused silica under this code into the EU is typically 3.0%, along with the standard Cypriot VAT rate of 19% (which registered companies reclaim via VIES). We supply full customs-cleared documentation including commercial invoices, detailed packing lists, certificates of origin (CO), and material purity certificates (COA).
How does fused quartz compare against silicon carbide (SiC), alumina (Al₂O₃), or graphite crucibles?
Fused quartz offers three distinct advantages: (1) Superior chemical inertness against molten silicon and acid reagents without carbon or aluminum contamination; (2) Exceptional thermal shock resistance — fused quartz can be heated to 1100°C and plunged into cold water without shattering, whereas alumina will fracture; (3) Optical transparency and low thermal conductivity compared to graphite, allowing visual observation of melts and reduced induction coil energy dissipation.
What is your Minimum Order Quantity (MOQ) for institutional or prototype testing in Paphos?
We actively support R&D departments, pilot lines, and university laboratories. For standard quartz crucibles, test tubes, and heating lamps, our MOQ is as low as 2 to 5 units to facilitate evaluation and fit checks. For custom large-diameter solar crucibles or CNC machined quartz blocks, we accommodate single-unit prototype manufacturing with full batch reproducibility upon scale-up.
What guarantee do you provide against transit breakage during sea or air shipment?
Kavri Quartz provides a 100% Zero-Breakage Guarantee. Each crucible is inspected, bubble-wrapped, nested within custom-molded shock-absorbing EPE foam, and sealed into rigid export-grade wooden crates. In the rare event of transit damage, simply provide a photograph of the damaged item and outer packaging upon delivery, and we will manufacture and dispatch a free replacement via expedited air courier immediately.
