Abstract:
A method for producing a silicon nitride honeycomb filter, which comprises heat-treating in a nitrogen atmosphere a green body comprising from 50 to 85 mass % of metal silicon particles having an average particle diameter of from 5 to 50 μm, from 5 to 30 mass % of glass hollow particles having a softening temperature of from 400 to 1000° C. and from 10 to 20 mass % of an organic binder to convert metal silicon substantially to silicon nitride.
