Study on the phosphorate minerals assemblage shows that strongly developed anatexis of the area is responsible the occurrence of wagnerite and its coexistence with apatite, and both present as rock-forming minerals. The volatiles F, P and components Ca, Mg determine the formation of wagnerite, while the P-T condition affects the variation of wagnerite polytypes.

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

In the condition of keeping F成人日韩在线综合观看、 K国内精品在线观看、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.
