The properties of Borosilicate 3.3 are specified in ISO 3585.
Very high chemical resistance, a high usage temperature, minimal thermal expansion and the resulting high resistance to thermal shock are its most significant properties.
This optimum physical and chemical performance makes Borosilicate 3.3 the ideal material for use in the laboratory and for the manufacture of chemical apparatus used in the industry.
It is also widely used on an industrial scale in all other application areas in which extreme heat resistance, resistance to thermal shock, mechanical strength and exceptional chemical resistance are required.
Quartzglass is an extraordinary material for numerous industrial applications. The single-component glass consists solely of silica (SiO2). Through its unique combination of thermal, mechanical and optical properties, quartzglass is an important material for industry and research.
Quartzglassproducts are used in high temperature processes because of its high softening point, low thermal expansion and excellent thermal shock resistance. It can withstand temperatures up to 1300°C and can be rapidly heated and cooled with virtually no risk of breakage. Because of its high purity, parts and systems made of fused quartz are ideal suited for industry equipment. Quartzglass is an indispensable material due to the high optical transmission from ultraviolet through the infrared light. Quartzglass is also used because of its resistance to acids, bases and water. With the exception of hydrofluoric acid, phosphoric acid, and alkaline compounds its properties are unaffected. Quartzglass is characterized by high dielectric strength, low electrical conductivity and superior microwave transmission even at high temperatures.
between stability and instability there's a magic moment.
