The physical and chemical indexes of the sight glass are as follows: Heat stability: 300 ℃ - 1500 ℃, can be used for a long time at 200 ℃ -1350 ℃ (dry burning) without burst

Transparency: <1100kg / cm2, resistance to hydraulic strength: room temperature and -80 ℃, 50kg / cm2; safe use of temperature: the use of special materials can be used for optical lens lens requirements; ≤1350 ℃; Chemical properties: Water resistance ISO0719 / DIN12111: HGB1; Acid resistance ISO1776; DIN12116: min3; Alkali resistance ISO0695 / DIN52322: A2.

       Thermal stability: The ability of a glass to be destroyed after severe temperature changes is called thermal stability. The greatest impact on the thermal stability of the glass is the stress distribution, in addition to the glass thickness, geometry, thermal expansion coefficient are closely related.

       Thermal shock strength: Thermal shock resistance is used to characterize the thermal stability of the size of the product is to keep the sample or not to be destroyed when the maximum temperature can be expressed.

       Refractive index: The refractive index can be understood as a decrease in the propagation velocity of electromagnetic waves in glass (based on the speed of light in vacuum). If the refractive index indicates the decrease in the speed of light, then: n = c / v where: n - the refractive index of the glass c - the propagation velocity of light in the vacuum v - the propagation velocity of light in the glass. The rate is 1.5 to 1.75.
