Our company manufactures synthetic quartz glass, which corresponds to the Chinese optical quartz glass grade ZS (JC/T 185-2013), formerly known as JGS1. It is produced via chemical vapor deposition (CVD), in which gaseous high-purity silicon tetrachloride is hydrolyzed and melted in a hydrogen–oxygen flame; larger‑size blanks further require high‑temperature tank‑melting to achieve the desired dimensions.
Gas-Refined Quartz Glass HP3002
Our company manufactures gas‑refined quartz glass, which corresponds to the Chinese quartz glass grade KS—formerly known as JGS2. Transparent quartz ingots are produced by melting high‑purity quartz sand in a hydrogen–oxygen flame; these ingots are then hot‑formed into larger, more uniformly structured quartz billets and slabs, which are subsequently processed into quartz wafers, flanges, and related products.
Corresponds to the quartz glass grade HS, formerly known as JGS3.
Milky White Quartz Glass HPR3004
Our company manufactures milky white quartz glass, using an air‑melting process to produce the opaque quartz glass HPR3004A, which can be processed into milky white quartz sheets. Additionally, we employ a rotary‑forming process to produce milky white quartz tubing with specialized wall thicknesses—HPR3004B—which is suitable for use as furnace tubes and as thermal insulation material.
Using a hydrogen–oxygen flame heat‑treatment process, quartz wafers, quartz flanges, and quartz tubes are precision‑shaped to meet customer specifications, yielding transparent quartz, milky quartz, and custom‑shaped quartz glass products. These include quartz boats, diffusion tubes, semiconductor cleaning tanks, and various quartz components, which are extensively employed in the semiconductor, photovoltaic, and optical fiber industries as critical materials.
Our company is equipped with a range of cold‑working machinery, including waterjet cutting, wire EDM, machining centers, and CNC lathes, enabling us to undertake the fabrication of quartz products tailored to diverse customer specifications.
Calcium fluoride single crystals offer the advantages of a broad spectral range, enabling operation from 155 to 7000 nm, along with a high laser‑damage threshold, low stress birefringence, and a high refractive index.
