Borosilicate glass is a type of glass made from silica (SiO₂) and boron oxide (B2O3), known for its excellent heat resistance and chemical durability. It can withstand high temperatures and resist corrosion from various chemicals, making it suitable for laboratory glassware, kitchenware, optical fibers, and applications in the electronics and optical industries.
Quartz glass is a high-purity silicon dioxide glass that offers excellent high-temperature resistance, chemical stability, and optical transparency. It withstands temperatures up to 1100°C, resists most chemicals, and provides superior light transmission from UV to infrared. Its low thermal expansion and strong mechanical properties make it ideal for laboratory equipment, optical devices, electronic components, and high-temperature furnaces.
High chemical durability for laboratory equipment such as beakers, flasks and scientific glassware
Employed in manufacturing equipment and components requiring high thermal and chemical stability.
Used for lenses, prisms and other optical devices that have strict requirements on glass purity, light transmittance and clarity
Quartz glass and borosilicate glass are essential in the chemical industry for their high resistance to thermal shock, chemical corrosion, and precise measurements.
Quartz and borosilicate glass are ideal for high-temperature appliances due to their superior thermal resistance and durability.
Quartz and borosilicate glass are essential in laser processing for their high thermal stability and precision. Ideal for optics, lasers, and high-power applications.
It has a slightly higher thermal expansion compared to high borosilicate glass. Despite this, it offers stable performance and cost-effectiveness for a variety of everyday and industrial applications. Corning EAGLE XG is one of the common typical models in market. Its durability and affordability make it a practical choice for both domestic and commercial uses.
It is heat-resistant and chemically durable, ideal for labs, optics, and solar panels due to its low thermal expansion. Common models include Schott BOROFLOAT® 33,DURAN®, 8337B, and Corning PYREX 7740, all known for their stability in extreme conditions and excellent thermal properties.
It is crafted from natural crystal or silica, with its quality hinging on the purity of the raw materials used. It typically contains a higher level of metal impurities and hydroxyl content compared to synthetic quartz glass, which can impact its optical and thermal properties.
Made from silicon compounds, offering higher purity and quality. Can be produced by PCVD, FHD, sol-gel, and other methods.Common models include Schott Lithosil®, Schott Vitrosil®,Corning HPFS® and Corning ULE®. These types of quartz glass are widely used in scientific research, industrial production and high-end optical systems.
The boron trioxide in borosilicate glass reduces the thermal expansion and increases its resistance to temperature shocks. When subjected to heat, the glass expands minimally, preventing cracks and breakage. Its chemical stability allows it to maintain its integrity even when exposed to corrosive substances.
Quartz glass is highly pure, which gives it exceptional thermal and optical properties. Its structure is more stable than borosilicate glass, allowing it to maintain its shape and clarity even under extreme conditions. The near-zero thermal expansion means it doesn’t deform or crack when subjected to rapid temperature changes.
