Description
1, high temperature.Quartz glass softening point temperature of
about ***0 ° C at ***0 ℃ for a long time, a short time maximum
temperature up to ***0 ° C, 2, corrosion-resistant. Except
hydrofluoric acid, the quartz glass is almost no chemical reaction
occurs with the other acids and its acid capacity is *0 times that
of the ceramic, stainless steel, ***-fold, especially in the
chemical stability at high temperatures, is any other engineering
materials are unable to match. 3, good thermal stability. A very
small coefficient of thermal expansion of the quartz glass, and be
able to withstand severe temperature changes, the quartz glass is
heated to about ***0 ℃, placed in water at room temperature and
will not burst. 4, the light transmission properties. The quartz
glass in the ultraviolet to have better light transmission
properties of the entire spectral band of the infrared, visible
light transmittance at *3% or more, particularly in the UV spectral
region, the maximum transmittance of up to *0 or more. 5, good
electrical insulation properties. Equivalent to one million times
that of ordinary glass, the resistance value of the quartz glass is
an excellent electrical insulating material also has good
electrical properties, even at high temperatures. Quartz glass
because of the excellent physical and chemical properties, it is
widely used in electric light sources, semiconductor, optical
communications, military, metallurgy, building materials, chemical,
machinery, electricity, environmental protection and other fields.
