Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.

However, lead-free relaxor ceramics with the bulk form exhibit low recoverable energy storage density (W rec < 2 J cm −3) owing to low dielectric breakdown strength (DBS <200 kV cm −1). Here we use a strategy (the transition liquid phase sintering) to decrease the porosity and increase DBS of lead-free relaxor ferroelectric …
