Open-architecture constituents, such as wood fibers, are coated with an intercalated functional material and bound together to form a solid product, such as a plank. Applications for this material include decking, fencing, and the like. The functional material is applied prior to forming the solid product, either as a coating on each fiber or inserted in a fiber or fiber cluster. As the constituents, such as fibers, wear during use of the product, the functional material is released to provide continual protection of the product, such as UV resistance and fungal resistance. |

The present invention relates to novel microporous zirconium silicate compositions having a desired particle size distribution and methods of making those compositions. These compositions have an ideal particle size distribution for use ex vivo, for example in a dialysis exchange cartridge, yet retain many of the desirable properties of prior improved absorbers including high cation exchange capacity. Further, the new zirconium silicate molecular sieve absorbers can be manufactured using a technique that achieves the desired particle size distribution while eliminating the screening step that was previously necessary. |

This invention relates to the synthesis of large pore composite molecular sieves and to the synthetic large pore composite molecular sieves so produced. The molecular sieves of the invention have the same general utilities of the comparable molecular sieves of the prior art but have been found to be superior catalysts and absorbents. This invention relates to a hydrothermal synthesis of large pore molecular sieves from nutrients, at least one of which contains an amorphous framework-structure, and which framework-structure is essentially retained in the synthetic molecular sieve. This invention stems from a discovery that the intrinsic porosity characteristics of a nutrient that possesses an amorphous cation oxide-framework can be substantially retained in the final molecular sieve containing product formed by a hydrothermal process by carefully controlling the conditions under which the hydrothermal process is conducted. For example, the invention contemplates retention of the particle size in a final molecular sieve-containing product that corresponds with that of an amorphous cation oxide-framework nutrient used in its manufacture. This invention drives the selection of process conditions to achieve one or more of macro and meso porosity (“large pore composite porosity”) in the final molecular sieve product as a direct product of the hydrothermal reaction producing the molecular sieve. The invention allows the production of a molecular sieve that is in situ incorporated in the framework morphology of a solid cation oxide-framework used in the molecular sieve's manufacture. |

The crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., and has uniformly sized pores with a maximum perpendicular cross section of at least about 13 .ANG.. In a preferred form, the support material, which is preferably a metallosilicate such as an aluminosilicate, has the pores in a hexagonal arrangement, giving rise to a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG.. |
