Zirconium acetate seems to be a very interesting zirconium precursor for the preparation of zirconium sulfate pillared clay because of its high and stable pH level and its low sensitivity to the precipitation when the sulfate was added. Nevertheless, the progress of the polymerization reaction is very rapid at high Zr concentrations, even at reduced intercalation temperature (15 °C). 

The oldest process known to yield zirconia fibers is the relic process [12] [83] [84]. The simplest process is a dry spinning process using a concentrated, aqueous solution of a zirconium salt [85-86]. Neither yields technically advanced fibers. The latter are best prepared by dry spinning and heat treatment of sol-gel derived or polyzirconoxane derived precursor fibers.
