Abstrakt:	The possibility of solving the problem of achieving uniform distribution in a ceramic charge based on silicon nitride of a small amount of oxide sintering additives using an ideal mixing model is considered. The mixing power necessary to prevent the separation of the mixture and obtain a homogeneous suspension during solvent removal is calculated based on a determination of the complex viscosity and the free deposition rate of silicon nitride particles in a mixture with organoyttroxanealumoxane (OYA) solution. The coefficient of heterogeneity (variation) calculated according to the analytical results confirmed that aluminum and yttrium oxides were uniformly distributed in the silicon nitride-OYA charge obtained as a result of implementing the ideal mixing model.
