Directly integrated from our Donghai facility, supporting precision semiconductor processes, vacuum optical assemblies, and extreme thermal applications.
A comprehensive evaluation of chemical inertness, trace elemental purity, and thermal boundary thresholds essential for advanced scientific vaporization vessels.
In analytical laboratories, geochemical exploration, battery metallurgy, and advanced semiconductor thin-film synthesis, the Quartz Evaporation Dish stands as an indispensable primary vessel. Unlike standard borosilicate glassware, which softens below 550 °C and leaches boron, sodium, and calcium ions into active solutions, high-purity fused silica (amorphous silicon dioxide) maintains complete crystalline and structural integrity under prolonged thermal stresses exceeding 1,100 °C and peak operational exposure to 1,250 °C.
Southeast Quartz synthesizes high-purity quartz evaporation dishes utilizing premium natural crystal sand and synthetic silicon tetrachloride precursors. The resulting fused matrix exhibits near-zero thermal expansion, enabling instant quenching and rapid thermal-cycle survivability. A dish heated to 1,000 °C can be submerged in ice-cold deionized water without experiencing tensile failure, phase crack propagation, or micro-fissuring.

Analyzing enterprise-scale deployment profiles for quartz evaporation vessels across high-technology manufacturing and strict regulatory testing workflows.
Ultra-pure quartz evaporation vessels are mandated across cleanrooms for ICP-MS and ICP-OES trace-element digestions. Testing UPW (Ultra-Pure Water) and semiconductor-grade mineral acids demands zero-ion-bleed vessels to ensure part-per-trillion (ppt) analytical accuracy.
With the global ramp-up in Lithium Iron Phosphate (LFP) and high-nickel ternary cathode production, quartz dishes serve as standard calcining crucibles and acidic concentration vessels for analyzing precursor purities of nickel, cobalt, and lithium salts.
Compliance with international pharmacopeial standards requires precise ash-residue quantification and heavy-metal screening. Fused silica evaporation dishes eliminate contamination, allowing reliable acid digestion and complete gravimetric recovery.
During granular polysilicon qualification and Cz-pulling process monitoring, samples must undergo continuous evaporation and hydrofluoric-nitric acid etchings. Our specialized thick-wall fused quartzware resists aggressive chemical digestion.
A disciplined six-stage fabrication architecture engineered to eliminate surface micro-cracking, bubbles, and particulate entrapment.
We leverage Donghai County's silicon supply chains, sourcing plasma-melted fused quartz ingots featuring exceptionally low hydroxyl (OH-) and transition metal content (< 8 ppm trace impurities).
Automated high-speed diamond slicing machines shape exact preform discs. CNC 5-axis ultrasonic contouring profiles standard, flat-bottom, spherical, and pouring-spout geometries with tolerances within ±0.05 mm.
Master glassblowers perform high-temperature fire forming at > 1,800 °C. Fire-polishing eliminates rough tooling micro-grooves, yielding an ultra-smooth, vitreous surface that prevents sample retention.
Vessels undergo programmed annealing at 1,150 °C inside vacuum atmosphere furnaces, followed by slow controlled cooling. This process releases internal mechanical stresses, preventing spontaneous thermal shatter.
All quartz dishes are treated in heated ultrasonic acid immersion tanks (Class 10,000 cleanroom) to strip surface contaminants and iron traces, followed by 18.2 MΩ·cm deionized water rinses.
Every batch is evaluated via laser interferometry for wall thickness uniformity, visual polariscopy for residual strain birefringence, and ICP-MS leaching testing prior to cleanroom vacuum packing.
