Abstract:
In a method for producing open-pore, ceramic-bonded grinding tools, a pore former mixture consisting of at least two polymers having different firing curves, the maxima of which differ by at least 20° C., is used. The polymers are preferably thermoplastics that can be decomposed exclusively into CO2 and water during combustion. The resulting grinding tool has a multimodal pore size distribution.
