A ceramic resin is provided, along with its methods of formation and use. The ceramic resin may include a crosslinkable precursor, a photoinitiator, ceramic particles, and pore forming particles. The ceramic resin may be utilized to form a ceramic casting element, such as via a method that includes forming a layer of the ceramic resin; applying light onto the ceramic resin such that the photoinitiator initiates polymerization of the crosslinkable precursor to form a crosslinked polymeric matrix setting the ceramic particles and the pore forming particles; and thereafter, heating the crosslinked polymeric matrix to a first temperature to burn out the pore forming particles.

The invention discloses a method for preparing mesoporous sound-absorbing material particles and mesoporous sound-absorbing material particles. The preparation method comprises the following steps. In step 1, sound-absorbing material powder and a templating agent are mixed with a binding agent and water to form sol slurry, the templating agent is an organic monomer or a linear polymer, and the templating agent has a purity greater than 95%. In step 2, the sol slurry is dropped into forming oil, and the droplets of the sol slurry are aged in the forming oil to form gel particles. In step 3, the gel particles are taken out from the forming oil and the gel particles are dried to form mesoporous sound-absorbing material particles. In step 4, the mesoporous sound-absorbing material particles are roasted.
