In the development of semiconductor manufacturing equipment, UHV (Ultra-High Vacuum) furnaces, and aerospace components, hardware engineers often face a critical material dilemma: relying on a single monolithic ceramic usually requires sacrificing one essential property for another.
“We need the extreme hardness of Alumina, but the thermal shock resistance and machinability of Boron Nitride.”
“Our thermal zone requires a dielectric insulator at 2000°C, but it must also possess high thermal conductivity to dissipate heat.”
“We need an inert material that can be precision-machined into complex threaded geometries with tolerances strictly held within ±0.01mm.”
Standard industrial ceramics struggle to meet these multi-dimensional requirements. Telite Ceramics addresses these complex thermal and mechanical challenges through advanced powder metallurgy and hot-pressing technology. Our latest series of Advanced Boron Nitride (BN) Composites provides tailored solutions for extreme operational environments.
1. The BN Composite Matrix: Engineering the Exact Material Grade
When R&D projects demand composite performance, Telite integrates the advantages of different ceramic powders to formulate specialized grades:
A. High Strength Meets Thermal Shock: BN + Si3N4 Composite
While pure h-BN is highly machinable and lubricious, it lacks structural rigidity. Our TLT-BM-57220-SM grade reinforces the BN matrix with Silicon Nitride. This elevates the compressive strength to a massive 400 MPa and flexural strength to 220 MPa. It is the optimal choice for high-stress nozzles and structural insulators subjected to heavy mechanical loads.
B. Dielectric Insulation Meets Rapid Heat Dissipation: BN + AlN Composite
Trapped heat is a primary cause of failure in high-frequency electronics. The TLT-BN-THUS AN grade maintains excellent high-temperature dielectric strength while pushing thermal conductivity to 85 W/m·K. It acts as an exceptional thermal management substrate for heating elements and electrode insulators.
C. UHV Stability Meets Absolute Purity: 99.8% Pure Hexagonal BN
For contamination-sensitive processes like Molecular Beam Epitaxy (MBE) and OLED deposition, we supply the TLT-B- -LG (99.8% Purity) and TLT-BN HP956-VG (99.5% Purity) grades. Capable of sustaining 2100°C and 1900°C in vacuum respectively, they exhibit zero outgassing and remain chemically non-wetting to most molten metals (Al, Cu, Ag).
D. Controlled Electrical Resistivity: Conductive TiB2 + BN
Engineered specifically for Physical Vapor Deposition (PVD), our EL Series (TLF-BN-EL & TLT-BN-ELC) provides highly dense (up to 3.2 g/cm³) conductive ceramic sources. These composites ensure stable evaporation rates for aluminum metallizing processes with extended service lifespans.
2. Precision Ceramic Machining: Pushing Tolerances to ±0.01mm
Premium material formulations must be paired with flawless execution. Research institutes and semiconductor equipment manufacturers frequently require highly complex geometries that cannot be molded.
Telite Ceramics operates an advanced multi-axis CNC diamond grinding facility. Our capabilities include:
✅ Micro-drilled high-temperature insulators and flanges
✅ Ceramic positioning rods with fine internal and external threads
✅ Complex thin-walled saggers and multi-cavity crucibles with interlocking lids
We consistently maintain dimensional tolerances within ±0.01mm. Even for extremely hard composites containing Alumina or Silicon Nitride, our proprietary tool path programming eliminates chipping, resulting in pristine surface finishes for UHV applications.
3. Custom Prototyping: Accelerating Global R&D
We understand that during the prototyping and pilot-plant phases, designs change frequently and quantities are strictly limited.
Telite Ceramics supports low-volume custom prototyping (starting from 1 piece). Our engineering team does more than read blueprints; we analyze your specific operational atmosphere, heating/cooling ramp rates, and chemical exposure to recommend the precise material grade that will minimize your development cycle costs.
