一、Carbon/Carbon Composite Materials：
High intensity; High heat resistance; Corrosion resistance; Good seismic performance; Low oxidation rate; Good processing performance. Applied to high-temperature and harsh chemical corrosion environments, such as materials in high-temperature furnaces in the semiconductor industry and other high-temperature equipment.
We can customize the size and shape according to the customer's drawing requirements, with lightweight and high strength. superior quality.
二、High density C/C insulation screen：
1、Main technical indicators
Density （g/cm3） | Bending strength (MPa) | Modulus of elasticity (Gpa) | Circumferential tensile strength (MPa) | compressive strength (MPa) | Coefficient of expansion （10-6/.K） |
≥1.4 | 100 | ＞25 | 80 | 150 | 1.5-2.5 |
2、Technical Characteristics
1. High fiber content: Made of pure carbon cloth (excluding mesh) through hot pressing and CVD densification, the finished product has a carbon fiber content of over 80%.
2. Compared to graphite insulation screens, it has higher strength, higher modulus, better seismic performance, lower thermal conductivity, and is less prone to cracking.
3. Surface strengthening layer: The surface has a high-purity and high-density strengthening layer, which is resistant to silicon corrosion, oxidation, and carbon pollution, and has a long service life.
三、Single crystal guide tube
1、Main technical indicators
Density （g/cm3） | Bending strength (MPa) | Compressive strength (MPa) | Thermal conductivity W/（m.k） | Coefficient of expansion （10-6/.K） | Ash content（ppm） |
≥1.5 | ≥120 | ＞220 | 40 | 1.5-2.5 | ≤200 |
2、Technical Characteristics
1. High fiber content: High pressure forming using pure carbon cloth (excluding mesh tire), CVD densification, resulting in a finished product with a carbon fiber content greater than 80%.
2. The material is uniform and the performance is stable.
3. Reinforcement layer: The surface has a high-purity and high-density (≥ 1.75g/cm3) reinforcement layer, which is resistant to silicon corrosion, oxidation, gas erosion, and has a long service life.
4. Adopting pure vapor deposition densification process, the problem of uneven density and structure of pure vapor deposition is solved through dedicated fixtures, with high densification efficiency; Simultaneously applying a rough layer pyrolytic carbon coating to reduce porosity and improve product lifespan.
