Glass Discs

"Glass Discs" is listed under  Gifts & Crafts Agents Category

Glass Discs with Good Thermal and Optical PropertiesGlass discs, whose material can be soda-lime, borosilicate or quartz, have different sizes and applications. The difference of soda-lime, borosilicate and quartz is the different content of silicon dioxide. The more silicon dioxide contain, the glass disc is stronger in thermal and optical properties.The diameter of our glass disc can be 5 mm to 1000 mm. The thickness can be 0.3 mm to 40 mm. Compared with other factory products, our glass discs surface is polished and no bubble and edge is exact round and polished. Whats more, Our glass discs can work in very high temperature as well as acid and alkali environment. In addition, as optical glass, our glass discs light transmittance can reach 93 Percent.With good thermal, mechanical and optical properties, the glass discs are widely used in instruments, LED lights, optical industry and so on.Four pieces of glass discs are on the ground and they are all bright, smooth and polished.GD-1: Our glass discs can be as thin as 0.3 mm and there is no bubble in them.One piece of glass disc stands on the ground.GD-2: Our thin glass discs have good optical properties and can also resist acid and alkali.SpecificationMaterial: soda-lime, borosilicate, quartz.Diameter: 5 mm - 1000 mm, according to customers requirements.Thickness: 0.3 mm - 40 mm.Surface handling: polishing, flat.Edge handling: grinding, polishing.Glass discs thermal propertiesMaterialSoda-limeBorosilicateQuartzSIO2 content60 Percent - 75 Percent> 81 Percent> 90 PercentDensity (25 & 176C)2.532.232.20Coefficient of thermal expansion8.6 & 215 10-63.3 & 215 10-65.5 & 215 10-7Softening point726 & 176C820 & 176C1780 & 176CMelting point780 & 176C1680 & 176C2000 & 176CAnnealing point546 & 176C560 & 176C1120 & 176CTemperature for short time working400 & 176C500 & 176C1500 & 176CTemperature for long time working350 & 176C450 & 176C1200 & 176CSpecific heat0.18 J/kg & 176C0.9 J/kg & 176C670 J/kg & 176CGlass discs optical propertiesMaterialSoda-limeBorosilicateQuartzIndex of refraction1.5231.4751.458TransmittanceThe different wavelength light transmittance of soda-lime glass disc.The borosilicate glass light transmittance of different thickness.The different wavelength light transmittance of quartz glass disc.Features and Advantages:Corrosion resistanceThe glass disc especially quartz can resist acid and alkali. The quartz do not react with any acid, except hydrofluoric acid.High working temperatureThe soda-lime glass discs can work under 450 & 176C high temperature and the quartz glass discs can even work under 1200 & 176C for a long time.High light transmittanceThe quartz transmittance can reach 95 Percent.Polished surfaceThere is no bubble or scratch and the surface is flat, clear and polished.Perfect edging handlingThe edge is exactly round. It can be ground and polished. The polished edge is more smooth.Five pieces of polished surface glass discs are on the desk.GD-3: Our glass discs are flat and polished in surface without any bubble.Two pieces of glass discs stands on the desk and the edge is smooth and polished.GD-4: We can handle the edge well and make sure it smooth and polished.Six pieces of polished surface glass discs in different thickness are on the desk.GD-5: Our glass discs are available in different thickness as your requirement.Two pieces of glass discs on the desk, one 0.5 mm thickness, another 5 mm thickness.GD-6: Glass desk 0.5 mm and 5 mm thickness.Application:As cover discs, they can protect from dust and moisture.Glass discs are used in optical industry because of its high transmittance.As cover glass and slides, glass discs are widely used in instruments.It is used in LED lights because of its good optical properties.Package and transportation:One piece in a plastic bubble bags and 100 bags in a carton and 10 cartons in
