Phosphorus Trichloride PCl3 and Phosphorus Oxychloride POCl3

Relationships between diffusion parameters and phosphorus precipitation during the POCl3 diffusion process

The POCl3 diffusion process is still a common way to create the pn-junction of Si solar cells. Concerning the screenprinting process, it is necessary to find a compromise between low emitter recombination, low contact resistance and high lateral conductivity. The formation of a homogeneous emitter during the POCl3 diffusion process depends on several diffusion parameters, including duration, te...

Synthesis of [32P]dolichyl phosphate, utilizing a general procedure for [32P]phosphorus oxychloride preparation.

Equilibration of the phosphorus in radioactive phosphoric acid with the phosphorus in phosphorus oxychloride occurs if these compounds are refluxed together for approximately 24 h. This observation led us to develop a method for the preparation of radioactive phosphorus oxychloride on a small scale with high specific radioactivity. The labeled phosphorus oxychloride may be utilized directly in ...

Thorium copper phosphides: more diverse metal-phosphorus and phosphorus-phosphorus interactions than U analogues.

To explore the chemical analogy between thorium and heavier actinides in soft anionic environments, three new thorium phosphides (ThCuP2, β-ThCu2P2, and ThCu5P3) have been prepared through solid-state reactions using CuI as a reaction promoter. The structure of ThCuP2 can be described as a filled UTe2-type with both dimeric P24- and monomeric P3- anions, in which Th is coordinated by eight P at...

Terrestrial phosphorus limitation: mechanisms, implications, and nitrogen-phosphorus interactions.

Nutrient limitation to primary productivity and other biological processes is widespread in terrestrial ecosystems, and nitrogen (N) and phosphorus (P) are the most common limiting elements, both individually and in combination. Mechanisms that drive P limitation, and their interactions with the N cycle, have received less attention than mechanisms causing N limitation. We identify and discuss ...
