The fritted glaze was melted at 1120℃,which was composed of boric acid and borax as mainflux,and the effect of chemical composition and process on glaze performance was discussed.

A series of red ceramic glaze were prepare with the addition of the negative catalyst and of the frit.

Be aimed at the defect of bubble in frit, the formation and growing of bubble nucleus, the dissolution and diffusion of the common gases, the rising and ejection of bubb1e in frit melt, and the factors that affect on them were mainly discussed in this paper.

The item is studied on the five-element-system ,which is mainly consisted by K_2O,CaO, Al_2O_3,B_2O_3 and SiO_2, through adding a few kinds of flux oxides, study them flux domino effect and their capability,find out them some change rules and forming-glaze’mechanism of R_2O-RO-Al_2O_3-B_2O_3-SiO_2 system, offer a way of study on bone-china ,which doesn’t contain lead-element.

By using fused magnesia and sintered spinel as main materials and sulphite liquor as binders,magnesium compound side gate was researched.

MgO-ZrO2 samples were prepared by fused magnesia and zircon.

In this paper, effect of properties of advanced magnesite-chrome brick on fine powder turning very small, the chromium concentrate powder and fused magnesia powder content, the amount of Zirconium dioxide to be studied identified RH furnace quality magnesite-chrome brick in the best process technique.
