XTL sintyron high purity 99.99% pbn ceramic VGF crucible

Molecular beam epitaxy (MBE) is one of the methods for the production of gallium arsenide epitaxy sheets, which can produce multi-component, multilayer, homogeneous, heterogeneous, superlattice and quantum well epitaxy materials. The crystal has high purity and good chemical stability. It is mainly used for the synthesis of semiconductor single crystal and Ⅲ-Ⅴ compound by MBE method.

High purity 99.99% pbn ceramic mbe crucible

It is different from ordinary hot pressed boron nitride (BN), does not have to go through the traditional hot pressed sintering process, does not add any sintering agent, so the obtained product has the following significant characteristics:

(1). Non-toxic, tasteless;

(2) High purity, up to 99.999% or more;

(3) At room temperature, it does not react with acid, alkali, salt and organic reagents, and is slightly corroded in molten salt and lye, but it can resist the corrosion of various acids at high temperatures;

(4) Do not react with most molten metals, semiconductors and their compounds;

(5) Below 1000℃, good antioxidant performance;

(6) Good thermal shock resistance, no cracks when put into water at 2000℃;

(7). High use temperature, no sublimation point, directly decomposed into B and N above 3000℃;

(8). High resistance, good electrical insulation performance;

(9) The surface is smooth, no porosity, and most semiconductor melts are not wet.
