We manufacture as per IS and BS Stand-ards.\n\na) There is little or no visible surface change or damage to silica with prolonged exposure to water, atmospheric gases, contaminants, oxide of nitrogen and ozone.\n\nb) Attack does occur, on exposure to alkaline solution and acids at very high temperatures.\n\nc) Low expansion and hence excellent dimensional stability and thermal shock resistance.\n\nResistant to chemical attack. Virtually unaffected by sulphuric, nitric and hydrochloric acids. Hot alkalies and certain metal oxides react on silica. It is attacked by hydrofluoric acid. At high temperatures, it is also attacked by phosphoric acid. Continuous use of fused silica above 10000C leads to devitrification with formation of crystobalite which is a crystalline phase and will lead to breakage on repeated use. For accurate and long use, it is advisable to wash the articles in distilled water and alcohol to remove trace impurities. Heating fused quartz to elevated temperatures causes Si02 to undergo dissociation. Consequently, when flame-working fused quartz, there is a brand of haze or smoke which forms just outside the intensely heated region. This haze presumably forms because the Si02 recombines with oxygen from the air (and perhaps water) and condenses as extremely small particles of amorphous Si02.", "price": 0.0, "discountamount": 0.0, "currencycode": "INR", "priority": 1000000, "isfreeshipmentavailable": false, "shipmentduration": 7, "_keywords": [ "air", "haze", "SiO2", "smoke", "brand", "ozone", "oxygen", "10000C", "little", "damage", "Heating", "Borosil", "alcohol", "nitrogen", "long use", "accurate", "breakage", "formation", "Resistant", "Quartz Ware", "Hot alkalies", "contaminants", "metal oxides", "dissociation", "fused silica", "repeated use", "crystobalite", "BS Stand-ards", "Low expansion", "heated region", "flame-working", "amorphous Si02", "Continuous use", "devitrification", "chemical attack", "small particles", "phosphoric acid", "distilled water", "trace impurities", "sulphuric, nitric", "high temperatures", "crystalline phase", "hydrofluoric acid", "alkaline solution", "atmospheric gases", "opaque Silica ware", "hydrochloric acids", "prolonged exposure", "desirable chemical", "visible surface change", "thermal shock resistance", "excellent dimensional stability", "weathering durability properties" ], "isarchived": false, "isavailable": true, "applicationid": null, "productindex": 2, "imageuri": "https://productimages.withfloats.com/actual/65588e1ce5241d558f074b97.jpg", "tileimageuri": "https://productimages.withfloats.com/tile/65588e1ce5241d558f074b97.jpg", "images": null, "totalqueries": 0, "gpid": null, "groupproductid": null, "createdon": "2023-11-18T10:12:40.72Z", "updatedon": "2023-11-18T10:12:40.72Z", "buyonlinelink": null, "producturl": "http://WWW.BJSCIENTIFICCO.COM//quartz-ware/2", "availableunits": -1.0, "iscodavailable": false, "isprepaidonlineavailable": false, "maxcodorders": 0, "maxprepaidonlineorders": 0, "uniquepaymenturl": null, "brandname": "", "category": "Quartz Ware", "tags": [ "Quartz Ware" ], "variants": false, "keyspecification": null, "otherspecifications": null, "pickupaddressreferenceid": "", "paymenttype": "None", "producttype": "products", "hsncode": null, "gstslab": 0.0, "isnotforsale": false }, { "_id": "65588dbfc8587c039085f87a", "fptag": "BJSCIENTIFIC", "merchantname": null, "customwidgets": null, "externalsourceid": null, "name": "Watch Glass", "description": "These Watch glasses possess high chemical durability thus preventing contamination of solution.
