Experimental The main starting materials were tabular corundum of various particle size and reactive alumina.
Table 1 Chemical composition of the main starting materials Al2O3 SiO2 Fe2O3 Na2O CaO Tabular corundum 99.7 0.02 0.13 0.14 0.05 Reactive alumina 99.8 0.03 0.02 0.08 0.02 The starting materials were weighed according to the predetermined formulation in table 2, dry- mixed, and then intimately wet-mixed with addition of 4% phenolic resin.
So the HMOR of the material is improved.
The reason is that with addition of Si3N4, the densification of materials decreased and the room temperature properties decreased.

Materials and methods Potassium bromate (KBrO3) was supplied to prepare the water samples containing a certain concentration of bromate.
A portion of UVC photon was blocked and absorbed by the suspended materials in the water, and the contaction of UVC and bromate was blocked up.
