Based on the typological study on the porcelain data,as well as the background of the economy in Sichuan and the porcelain producing technique all over China in that period,the writer studied the porcelain and the handicraft industry of producing porcelain in Sichuan in Song Dynasty in different aspects,including configuration of the porcelain,the technique and the background of the society economy.
In this dissertation, we selected the most prevalent SQL Server2000 database as back-end server and Delphi7 as developing tool, developing management system about high-quality porcelain wares and ancient ceramic database.
The ingredient of Yunnan coal kaoline ceramic tile blank was determined by using K_2O-Al_2O_3-SiO_2 phase graph. The final ingredient was Eshan pre-calcined coal kaoline 21.57%, porcelain clay 23.20%, Eshan clay 55.15%.
1. The syntheses and analyses of a special porcelain used to titanium and its alloysTo develop the special porcalain used to titanium and its alloys, SiO_2 — A1_2O_3—B_2O_3—Na_2O—K_2O glass was chosen as the matrix and some other chemical compositions were used as the additives.
After the treatment in acetone, ethyl acetate, 95% alcohol and 1% HF before firing of porcelain with Ti 75 alloy, the shear bond strength were 57.80MPa, 55.75MPa,55.62MPa and 25.98MPa respectively, and it was 28 34MPa for the control group.
Results The shear bond strength of porcelain with pure titanium after the treatments in acetone, ethyl acetate, 95% alcohol and 1% HF were 53.29MPa 52.54MPa, 50.69MPa and 21.18MPa respectively, and it was 26.75MPa for the control group.
Methods Ni-Cr alloy (Germany), at the thickness of 0.3mm and VMK 95 METALL KERAMIK, A2 porcelain was used to make the PFM samples, with the porcelain thickness varying from 0.5 to 2.5mm (divided into 5 groups, 10 samples in each).
方法 选用VMK 95 METALL KERAMIK,A2色瓷粉,Ni-Cr非贵金属体系烤瓷合金(德国),常规制作金瓷试件(金属基底厚为0.3mm,瓷厚度分别为0.5mm,1.0mm,1.5mm,2.0mm,2.5mm各10个试件,分成5组)。
1. Experimental study of effect of Captek basis on color of baked porcelain prosthesisThree basis alloys-Captek, Pentron Bio86 and Ni-Cr and two kinds ofporcelain power - Ivoclar and Ceramco were selected to make 6experimental groups of 庐7mmx0.5mm Captek/Ivoclar, Captek/Ceramco,Pentron Bio86/Ivoclar, Pentron Bio86/Ceramco, Ni-Cr/Ceramco andNi-Cr/Ivoclar and 2 control groups of two kinds of porcelain powerwithout basis respectively.
