Stabilized, delaminated phyllosilicates as disclosed, and a method of producing the same, wherein the phyllosilicate is heated in the presence of a reactive vapor phase, preferably a hydrogen-containing atmosphere. The delaminated phyllosilicate is less than 1000Å thick, and is stabilized against moisture pickup. The formation of either a layer of a transition metal, or an organic reactive site, on the phyllosilicate surface is also disclosed.
Also disclosed is a delaminated phyllosilicate particle of less than 1000Å thickness and having a coating of metal on its surface, the metal being selected from the transition elements and groups 3a, 4a, 5a and 6a of the Periodic Table. A method of producing such particle is shown, by an ion exchange treatment coupled with a reactive vapor phase/thermal treatment. A ceramic-metal composite composed of such metal coated particles compressed in a solid body is also disclosed.
所公开的稳定分层植硅体及其生产方法,其中植硅体在反应气相(最好是含氢气氛)存在下加热。分层的植硅体厚度小于 1000埃,并具有稳定的防潮性能。此外,还公开了在植硅体表面形成过渡金属层或有机活性位点层的方法。
此外,还公开了一种厚度小于 1000Å 的脱层植硅酸盐颗粒,其表面有一层金属涂层,金属选自过渡元素和元素周期表中的 3a、4a、5a 和 6a 族。图中展示了通过离子交换处理和反应气相/热处理生产这种颗粒的方法。此外,还公开了一种陶瓷-金属复合材料,由压缩在固体中的这种金属涂层颗粒组成。
