difference between quartz glass and high borosilicate glass

Composition: Quartz glass is over 99% silica, while borosilicate glass contains around 80% silica.
Temperature resistance: Quartz glass can withstand much higher temperatures (up to 1,100°C), while borosilicate glass can resist up to 450°C.
Hardness: Quartz glass is harder than borosilicate glass.
Heat conduction properties: Quartz glass has better heat conduction properties.
Corrosion resistance: Borosilicate glass is more corrosion-resistant.
Application areas: Quartz glass is used in optics and semiconductor devices, while borosilicate glass is used in ceramics and refractory materials.
