Quartz Glass Clear Quartz Glass Round Quartz Glass

Specifications:
Round temperature resistance glass
1)High purity quartz ,SiO2> =99.99%
2)no bubble, strip, chipping or scratch
3)we can manufacture the quartz products according to customer’s design
Features of round temperature resistance glassas follow:
1.High purity made of 99.99%-99.9999% pure quartz.
2.Strong Hardness, Can reach Morse level 7.
3.High temperature resistance, canworkunder1200°Ccontinuously,andin shorttime canevenworkunder1500°C.
4. Acid and Alkali resistance
