PV Carbon-Ceramic Thermal Insulation Liners

PV carbon-ceramic thermal insulation liners are typically placed outside the crucibles in the photovoltaic hot zone system, together with the components such as crucibles, flow guide cylinders and heating components. Primarily serving the functions of auxiliary insulation, heat isolation, and structural support, PV carbon-ceramic thermal insulation liners can help maintain the temperature uniformity and stability within the photovoltaic hot zone, thus providing the suitable operating conditions for silicon melting and growth.

Semicorex PV carbon-ceramic thermal insulation liners are made of the high-performing carbon-ceramic composite materials. This kind of materials perfectly combines the excellent strength and toughness of carbon fiber with the exceptional high temperature resistance, corrosion resistance, and low coefficient of thermal expansion of silicon carbide ceramic. This integrated properties endows Semicorex PV carbon-ceramic thermal insulation liners with remarkable in-service performance.

The Performance of Semicorex PV carbon-ceramic thermal insulation liners

1.Strength and toughness performance

The reinforcing effect of carbon fiber significantly improves the flexural strength, compressive strength and fracture toughness of Semicorex PV carbon-ceramic thermal insulation liners, which enables them to withstand mechanical and thermal stresses in polycrystalline or monocrystalline hot zone.

2.Thermal insulation performance

Semicorex PV carbon-ceramic thermal insulation liners boast low thermal conductivity, which can effectively avoid heat loss within the thermal field of photovoltaic polysilicon/monocrystalline silicon manufacturing, thereby improving the quality and efficiency of crystal growth.

3. Thermal stability performance

Semicorex PV carbon-ceramic thermal insulation liners have superior high-temperature resistance and a low thermal expansion coefficient. With these properties, they can maintain their dimensional stability and shape integrity even when exposed to temperatures up to 1500°C, while remaining impervious to damage caused by sudden thermal shock.

The Applications of Semicorex PV carbon-ceramic thermal insulation linersPV carbon-ceramic thermal insulation liners are widely used in the hot zone systems of monocrystalline and polycrystalline silicon manufacturing in the photovoltaic industry. Thanks to their high performance and long service life, they can replace traditional graphite and carbon-ceramic components as upgrade alternatives to retrofit and enhance photovoltaic thermal field systems.
