Ceramic particle filter partially made from porous silicon carbide for filtering exhaust gases from diesel engines has a surface region made from silicon carbide particles which grow to form a rigid network
Ceramic particle filter partially made from porous silicon carbide for filtering exhaust gases from diesel engines has a surface region made from silicon carbide particles which grow to form a rigid network
Ceramic particle filter partially made from porous silicon carbide has a surface region (1) made from silicon carbide particles (2) which grow to form a rigid network. The network is orientated to the position, shape and length of short fibers introduced. (1) Has a pore volume of 60-95 % and is connected to a further region (3) made from porous silicon carbide with a pore volume of 20-60 %. An independent claim is also included for a process for the production of a ceramic particle filter by pyrolysis a polymer and/or natural fiber and sintered under vacuum at 2000-2500 [deg]C.
