Carbon/carbon composite guide tube

Carbon/carbon (C/C) composite guide tubes are primarily used in the growth of monocrystalline silicon, where they play a role in establishing the temperature gradient necessary for crystal growth and guiding the flow of gases. Within the thermal field, they direct the flow of gases, preventing external heat from conducting to the interior, and form a temperature gradient suitable for monocrystal growth, which increases the growth rate of the silicon ingot.

Carbon/carbon fasteners

Carbon/carbon fasteners are machined from carbon-carbon rods or plates and possess the excellent properties of carbon-carbon composite materials. They are widely used in the photovoltaic and semiconductor thermal fields for connecting and fastening, suitable for assembly in high-temperature vacuum furnaces and for high-mechanical-strength connections in critical areas.

Carbon/carbon aircraft brake disc

Aircraft brake discs are made from carbon/carbon composite materials, primarily used for deceleration and braking of aircraft on the runway. They have several performance characteristics, including lightweight (with a density one-third that of metal brake discs), high-temperature resistance (capable of withstanding temperatures above 2000°C), high specific strength, high specific modulus, corrosion resistance (able to endure erosion from various acids, alkalis, and salts), high friction coefficient, and wear resistance. These features meet the comprehensive performance requirements for braking materials of various aviation vehicles under high-speed and high-temperature conditions.

Carbon/carbon electrode column

Carbon/carbon electrode columns are used in the thermal fields of photovoltaic and semiconductor monocrystalline silicon. They serve to connect the heating elements inside and outside the thermal field to the water-cooled copper electrodes, and are used in conjunction with the bottom heaters. They have the advantages of low thermal conductivity, uniform resistance, excellent thermal shock resistance, and long service life; they can continuously provide energy-saving and consumption-reduction for the growth of photovoltaic and semiconductor monocrystalline silicon.

Carbon/carbon heater

Carbon/carbon heaters are widely used in the growth of monocrystalline silicon in photovoltaic and semiconductor crystal growth furnaces, working in conjunction with the main heater to control the temperature of the thermal field, in order to meet the temperature requirements for melting materials and crystal growth. They are characterized by excellent thermal shock resistance, uniform resistance, resistance to thermal shock, long service life, and other advantages.
