Knitted precious metal textiles such as wire gauzes, and methods of making the same, are disclosed. The textiles are suitable for use in catalysis, and are especially useful for the catalytic processing of ammonia. Particularly preferred knitting stitches are tricot, jacquard and raschel. Rotary or circular knitting machines may be used, but warp knitting machines are preferred for most applications. Advantageous products produced by the knitting process are described. These products include layers of non-uniform thickness, and uncut products having non-parallel side edges, such as circles. |
