Product Description

 

Pyrolytic boron nitride (PBN)belongs to the hexagonal crystal system and is an advanced ceramic material with a purity of
99.999%. It is formed by chemical vapor deposition (CVD) of ammonia and boron halides under high temperature and high vacuum conditions. It can not only be made to PBN sheets, but also made to PBN final products such as crucibles, boats, and coatings. 

 

Main feature
Unlike ordinary hot-pressed boron nitride (BN), it does not need to go through the traditional hot-pressing sintering process and does not add any sintering agent, so the obtained product has the following remarkable features:
* Non-toxic and tasteless;
* High purity, reaching more than 99.999%;
* It does not react with acids, alkalis, salts, and organic reagents at room temperature, and is slightly corroded in molten salt and lye, but can resist the corrosion of various acids at high temperatures;
* Not reactive with most molten metals, semiconductors, and their compounds;
* Below 1000 , the anti-oxidation performance is good;
* Good thermal shock resistance, no cracks are seen in the water at 2000°C;
* The use temperature is high, there is no sublimation point, and it is directly decomposed into B and N above 3000 °C;
* High resistance and good electrical insulation performance;
* The surface is smooth, without pores, and does not wet with most semiconductor melts 

 

Applications

* OLED evaporation boat
* Semiconductor single crystal growth (VGF, LEC) Crucible
* Molecular beam epitaxy (MBE). Evaporation crucible
* MOCVD heater
* Polycrystalline synthetic boat
* PBN infrared window
* Satellite communication microwave tube
* PBN coated carrier plate
* High temperature, high vacuum equipment insulation plate

 

Characteristic 

--- 

 

1.The Color of PBN is between ivory and orange-brown,nontoxic,imporisuty,easy processing. 

2. The purity is up to 99.99%,surface densification,good gas barrier properties. 

3.Tge strength increase as temperature rises and peaked at 2200. 

4.Acid,alkali,salt and organic reagent resistant.Meanwhile,it does not react with the majority of molten-

metal and semiconductor material. 

5.Excellent thermal shock resistance,excellent thermal conductivity,low thermal expansion coefficient. 

6.High resistance,high dielectric strength.low dielectric constant.low dissipation factor,excellent 

microwave and infrared ray ability. 

7. It's with anisotropy in the mechanics,heat and electricity.
