Abstract
There is disclosed a porous inorganic material, suitable for use as a support material for biological macromolecules, comprising substantially spherical particles of an aluminosilicate ceramic material, any internal cavities present in a particle occupying no more than 10% of the volume of the particle, each particle having a diameter in the range of from 5 micrometers to 5 millimeters and consisting predominantly of an open three-dimensional matrix of needles of the ceramic material each of which needles has a length in the range of from 2 to 20 micrometers and a width in the range of from about 0.2 to 2 micrometers, the ceramic needles defining between them interconnecting pores of width of from 0.1 to 5 micrometers. Also disclosed is a method of preparing such a porous inorganic material.
