Shiga hpe tawn da u

 

A

Quartz glass hpe san seng ai shingra tara amyu myu hpe hka ja ai hku nna galaw ai.

Shi a thermal expansion a coefficient gaw grai n law ai, 1/10 kaw nna 1/20 du hkra sha, shinggyim masha ni a shingnip shingna rai nna, shi gaw grai kaja ai thermal shock hpe ninghkap lu ai. Dai hta n-ga, grai katsi ai- hpe mung grai katsi ai, 1100℃kaw nna 1200℃du hkra 1200℃hte 1400℃du hkra bungli galaw ai nbung katsi ai lam ni hpe hkam sharang lu ai.

Quartz glass hpe madung hku nna laboratory arung arai ni hta lang ai rai nna, laksan tsaw ai{0}} ni a laksan arai ni hpe gram lajang ai hta mung jai lang ai. Shi a spectral transmitance gaw, radiation hkra machyi ai lam (radiation hte hkrum katut ai shaloi, nsin sin ai kaga myi man magap ni) hpe n-gun n rawng hkra galaw ya ai majaw, lamu ga ntsa na sanghpaw li, nbung n-gun rawng ai hkuwawt ni, spectrophotometer optical system ni hta lang na matu grai kaja ai.
Quartz glass gaw silicon dioxide hte sha galaw da ai laksan hpaga lam a glass langai mi re. Shi gaw grai n-gun ja ai, Mohs 7 de du wa ai, n-gun kaba ai{2}} n-gun n-gun n-rawng ai, nbung n-gun n-gun n law ai, n-gun n law ai thermal shock hpe ninghkap lu ai, chemical stability, hte wan n-gun hpe n-gun n-gun n-rawng ai atsam ni hpe grai kaja hkra galaw lu ai atsam ni nga ai.

Dai gaw ultraviolet hte infrared nhtoi ni hpe mung asan sha mu lu ai. Dai gaw, hydrofluoric acid hte katsi ai phosphoric acid hpe lai nna, common acid ni hpe atsawm sha ninghkap lu ai atsam hpe madun dan ai. Dai hpe asan sha nga ai hku nna lahkawng hku garan nna garan ginhka ai. San seng ai lam hpe tsaw ai- san seng ai lam, shinggyim masha ni, hte doped ngu ai daw masum hku garan ai. Dai hpe crystal, silica, silicide ni kaw na galaw ai rai nna, n-gun kaba ai{5}} hpe n-gun n rawng ai (sh) chemical vapor deposition hku nna galaw ai. Melting ladat ni hta wan n-gun hte gas hpe gram lajang ai lam ni lawm ai.

Fused Silica amyu myu nga ai, n bung ai application ni a matu lang ai. Anhte hta madung hku nna amyu masum nga ai, dai hta JGS1, JGS2, JGS3 ni lawm ai.

 
 
JGS1 (UV Optical Quartz Glass makau)Dai gaw SiCl 4 hpe raw material hku nna galaw ai optical quartz glass langai mi rai nna, san seng ai oxyhydrogen wan n-gun kaba hte hka lim mat ai. Dai majaw, dai hta hydroxyl law law lawm ai (2000 ppm grup yin) rai nna, UV transmission galaw ai lam grai kaja ai. Grau nna, hka leng UV ginra kadun hta, shi a htawt sit ai lam gaw kaga glass amyu yawng hta grau kaja ai. 185nm hta UV kap bra ai lam gaw 90% (sh) dai hta jan ai de du lu ai. 2730 nm hta synthetic quartz glass gaw grai n-gun ja ai hkap la ai lam hpe lu la nna, particle structure n nga ai. Dai gaw 185{{18}25000nm lapran na kaja dik ai optical material langai mi re. JGS1 hpe sung ai UV hte mu lu ai wavelength range Laser, Lenses, Windows, Prisms hte Mirrors, etc. ni hta galaw ai optics ni a matu lang ai. JGS1 Fused Silica gaw lawu na Manufacturer Heraeus – Suprasil 1 hte 2 San Pra ai-Gobain hte bung ai.

JGS2 (UV Optical Quartz Glass)
Dai gaw quartz glass rai nna, n-gun n rawng ai arung arai hku nna, n-gun rawng ai nhprang arai ni hpe bang nna, PPM metal n san seng ai lam law law lawm ai. 2730nm hta hkap la ai lam a npawt nhpang (hydroxyl 100-200ppm) nga ai, stripe hte particle structure ni nga ai. 220-2500 nm ngu ai wave band lapran na kaja ai arung arai langai mi re. Akyu ni hta JGS1 hte bung ai UV hte mu lu ai transmission ni lawm ai. Grai n-gun n rawng ai hte bubble n lawm ai diameter kaji/dimensions ni hta galaw mai ai. Cons ni hta byin mai ai bubbles ni hpe grau kaba ai dimension/diameters ni hta lawm ai.
JGS2 Fused Silica gaw lawu na Manufacturer ni hte maren sha rai nga ai
Herraeus a Nta 1,2; 3
Dynasil 1000; 4000; 5000; 6000
JGS2 a matu jai lang ai lam ni gaw:
condenser myi man ni hpe;n-gun ja ai hte n-gun n-gun rawng ai jak ni
optical flats;Microscope slide ni;mu lu ai myi man

3. (Infrared Optical Quartz Glass) JGS3
JGS3 gaw ultraviolet, mu lu ai hte infrared spectral ginra ni hta dan dawng nga ai. 185-250 nm spectral ginra hta nga ai, raitim, sung ai UV hte IR wavelength range hta grai dan dawng ai optical arawn alai ni lawm ai, mu lu ai hkum hkrang atsam ni hta absorption band ni n nga ai. DUV kaw nna MIR du hkra grai dam lada ai wavelength ra ai ni rai nga ai. Silicon hta loi mi manu dan ai hte Calcium Fluoride (sh) ZnS Multi-spectral grade hta loi mi manu n law ai.JGS3 gaw lawu na galaw shapraw ai ni hte maren sha rai nga ai Heraeus Suprasil 300.
