Performance Feature of Quartz Structural Parts
Thermal performance: compared with ordinary ceramics and refractory materials, it not only has smaller linear expansion coefficient and high temperature creep, but also has good thermal stability and aging resistance.
The thermal conductivity of quartz structural parts is low and the contact thermal resistance is large. When the temperature is higher than 1200 ° C, it increases exponentially.
It is precisely because of the low linear expansion coefficient of quartz structural parts, so it also has quite good thermal stability.
Chemical stability: Quartz structural parts have good chemical stability (in addition to hydrofluoric acid and hot concentrated sulfuric acid above 300℃ erosion) hydrochloric acid, sulfuric acid, nitric acid and other quartz structural parts have almost no effect.
Metal melts such as lithium, sodium, potassium, rubidium, and cesium also have little effect on quartz structural parts. And its resistance to glass acid erosion is also very good.
Electrical properties: The electrical properties of quartz structural parts are very good. The resistance is also very large, and its dielectric constant is much lower than the electrical loss Angle tangent with temperature changes are alumina and other high temperature ceramics,
which can be used as insulation materials, but also a good material for missiles and radar radomes.
Bending and compression resistance: the difference between quartz structural part and other ceramics is that the flexural strength and compressive strength of quartz structural parts are greatly increased with the increase of temperature,
because the plasticity of fused quartz structural parts increases with the increase of temperature, and the brittleness decreases.
Nuclear performance: The nuclear properties of quartz structural parts are also very good. The coefficient of thermal expansion is very small,
so the structure is stable compared with other materials under radiation conditions. In addition, the strength of quartz structural parts is basically not affected by nuclear radiation,
and has a low thermal race capture cross section, so it is widely used in atomic industry and radiation laboratories.
Application Range for Quartz Structural Parts
1. The metallurgical industry: quartz structure part has been widely used in nonferrous metallurgy because of its extremely low expansion coefficient and high thermal stability.
2. Electrical industry: quartz structure part has the characteristics of dielectric strength, fire resistance and heat resistance, so it can be applied in electric insulation and light wave reflector.
3. Float glass industry: quartz structure part has the advantages of small thermal conductivity, good thermal shock stability, small thermal expansion coefficient and no easy to adhesion with tin ash and debris,
which can obviously improve the surface quality of glass.
4. Glass deep processing: The characteristics of quartz structural parts can fully meet the requirements of usage of the production of high-quality tempered glass.
5. Aviation: It can be used in the nozzle, head and front chamber of the rocket engine, and is one of the missile radome materials widely used at domestic and aboard.
It is also widely used as an optical reflector in the radio telescope, and is also a high-quality infrared reflector.
6. Precision platform: The chemical advantages performance of quartz structural parts can make the thermal deformation of the precision platform smaller,
and the deformation caused by the internal stress because of the thermal expansion of quartz is much smaller than that of aluminum, steel and alumina,
so it has become an ideal precision material for the production of precision platforms.
7. Crucible: In the solar industry, the quartz structure crucible is a key component of the polycrystalline silicon ingot furnace for solar cells, which acts as a container for loading polycrystalline raw materials.
