Abstract:

Disclosed are various embodiments that include a process, an arrangement, and an apparatus for boron diffusion in a wafer. In one representative embodiment, a process is provided in which a boric oxide solution is applied to a surface of the wafer. Thereafter, the wafer is subjected to a fast heat ramp-up associated with a first heating cycle that results in a release of an amount of boron for diffusion into the wafer.

Abstract:

A novel process for bleaching cellulosic pulp is disclosed which provides improvements in pulp brightness and delignification without negatively impacting physical properties of the pulp. Specifically, a process is disclosed in which kraft pulp is treated with at least one of each of an oxidizing agent, an alkaline agent, and a metal substituted xerogel in a bleaching stage to improve brightness and delignification of softwood, hardwood, or recycled pulp. In a preferred embodiment, a process is disclosed which uses at least one metal substituted xerogel as a catalyst in an alkaline peroxide bleaching stage to improve kraft pulp brightness and delignification. Pulps bleached according to the process of the present invention are also disclosed.
