Ceramic casting method and formulation
A method of casting an aluminium nitride (AlN) ceramic component, comprising providing an aluminium nitride ceramic slurry, slip casting a green product using the slurry, and sintering the green product to dry to produce the aluminium nitride ceramic component, wherein the slurry comprises an aluminium nitride powder, a solvent, and a polymer binder, wherein the slurry comprises no more than 5 wt% polymer binder. The polymer binder may comprise polypropylene carbonate, and the solvent may comprise DMP, DMC, MEK or NUP. The slurry may further comprise a dispersant comprising an isobutyl methacrylate and/or a phosphate ester. The slurry may comprise one or more additional ceramic additives. A lubricant may be applied to the slip casting mould surface, and electronic components may be arranged on the mould surface so that the electronic components are embedded in the green product after slip casting. The green product may be used as a further slip casting mould to slip-cast a further layer of ceramic slurry to produce a laminated green product. The aluminium ceramic component may be a heater component. An aluminium nitride ceramic slurry for use in slip casting an aluminium nitride ceramic component is also defined.
