Since 1975, the Australian scholar K.C.Ganvil first proposed the new concept of using the volume effect produced by the phase transformation of zirconia ZrO2 to achieve a new concept of toughening ceramics, the research on zirconia has become very active.

Zirconia hollow sphere products and hollow sphere bricks are made of zirconia hollow spheres by electrofusion method. Binder is added to the zirconia hollow spheres, and zirconia hollow sphere products are made by molding and firing. Zirconia hollow spher

When it comes to the difference between corundum and corundum mullite, let us first talk about the properties of the two raw materials, corundum and mullite; the main component of corundum is α-Al2O3, which belongs to the triangular crystal system, and th

For sintering, the sintering temperature generally reaches above 1200 °C, which requires higher requirements for the setter. Domestic materials generally have a series of problems such as low scale, different powder particle size, high impurity content, a
