High Purity Quartz Supplier & Exporter in Mandalay

Fused quartz is manufactured by melting naturally occurring high-purity quartz crystal sand (SiO₂ ≥ 99.99%). It delivers exceptional thermal stability up to 1,450°C, structural strength, and near-zero thermal expansion at an economical price point, making it ideal for mining assay crucibles, gemological furnace tubes, and furnace viewports in Mandalay. Synthetic fused silica is produced via chemical vapor deposition of silicon tetrachloride (SiCl₄); it features virtually zero metallic impurities and superior transmission into the deep ultraviolet spectrum (DUV < 200 nm), recommended for sub-micron semiconductor photomasks and specialized spectrophotometer cuvettes.

Devitrification (transformation from amorphous silica glass into crystalline cristobalite) occurs when quartz is held at temperatures exceeding 1,150°C in the presence of surface contaminants such as fingerprints, alkali dust, or flux residues. To maximize tube life during gem treatment in Upper Myanmar: (1) Always handle quartz tubes with clean cotton or lint-free gloves; (2) Pre-wash the surface with a 5% hydrofluoric (HF) acid rinse followed by deionized water before furnace loading; (3) Specify our low-hydroxyl (≤ 15 ppm OH^-) flame-annealed quartz tube series to minimize internal molecular restructuring.

For urgent factory maintenance and small-to-medium consignments, cross-border express transit via the Yunnan-Muse overland corridor down the AH14 to Mandalay delivers orders in 5 to 9 business days, bypassing Yangon port handling. For container-load orders (such as large-diameter furnace tubes, quartz sand, or bulk crucibles), ocean shipping from Lianyungang or Shanghai Port to Yangon (Thilawa Port), followed by bonded rail or truck transit to Mandalay dry ports, offers the lowest freight cost per unit. Every shipment is insured and packed in shock-cushioned wooden crates.

No. Fused quartz is completely inert to virtually all acids, including concentrated nitric acid, sulfuric acid, hydrochloric acid, and aqua regia. However, hydrofluoric acid (HF) directly reacts with silica to form fluorosilicic acid, dissolving the glass matrix even at ambient temperatures. Concentrated phosphoric acid also initiates surface etching at temperatures above 150°C. For mining assays involving complex silicate dissolution via HF digestion, PTFE or platinum labware should be substituted; for all other acid evaporations and ashings, quartz remains superior to porcelain and borosilicate.

Yes. Over 70% of our production consists of OEM and ODM custom components. We produce standard taper ground joints (e.g., 14/23, 24/29, 29/32, 45/50), ball-and-socket vacuum joints, custom-machined end flanges, gas injection ports, and optical sight ports. Simply supply your engineering drawings in PDF, DWG, or DXF format, and our engineering department will verify dimensional tolerances and machine capability within one hour.

We accept Telegraphic Transfer (T/T), confirmed irrevocable Letters of Credit (L/C at sight), and cross-border bank wire transfers in USD, EUR, and CNY. We supply full documentation required for Myanmar commercial customs clearance, including Commercial Invoices, Detailed Packing Lists, Certificates of Origin (CO), Mill Test Certificates (MTC) certifying chemical composition and purity, and Bill of Lading / Airway Bills.
