Uses of graphite heaters

Полупроводниковая промышленность

In the semiconductor chip manufacturing process, silicon wafers need to undergo complex heat treatment. When the wafer is annealed, graphite heater eliminates the internal stress of the silicon wafer and avoids warping deformation with precise temperature control ability. In the epitaxial growth process, it creates a stable high temperature environment. So that the atoms are orderly arranged according to the lattice structure. It greatly improves the chip manufacturing accuracy and yield, and lays the foundation for the stable performance of the chip.

Металлургическая промышленность

You can use its high thermal conductivity to quickly heat the metal to the melting point,  shortening the melting cycle. During the purification phase, its chemical stability prevents contamination of the metal and ensures purity. In the casting process, graphite heater accurately controls the temperature, makes the metal liquid evenly fill the mold, reduces internal defects. It improves the quality of metal materials, and meets the strict requirements of different industries for metals.

Scientific research experiment

It provides a stable heat source for high-temperature chemical reaction experiments. And it helps researchers observe the reaction path and product changes of substances at high temperatures. In material performance testing, it precisely regulates the temperature, helping new material development and performance optimization.

New energy battery manufacturing

When the электрод material is sintered, it uniformly heats the material to make the crystallization denser and increase the energy density of the battery. In the drying process, you can use graphite heater to quickly remove water to avoid water affecting electrode activity. And optimize battery charging and discharging efficiency and cycle life.

Glass manufacturing

It can heat the liquid glass locally, accurately adjusting the viscosity and fluidity of the liquid glass, so that the glass is evenly extended. In the manufacture of optical glass, it stabilizes temperature control, reduces the internal stress of the glass. It effectively reduces optical distortion, and produces glass products with smooth surface and excellent optical properties.
