Abstract


This article briefly discusses the PDP Research substrate glass , performance requirements and application prospects . According to the literature , the proper adjustment of the composition , the R20-RO-Al2O3-ZrO2-SiO2 and Influences of R2O -RO -Al2O3 -B2O3 -ZnO -ZrO2 -SiO2 both glass system composed of design with orthogonal experiment method , with a high temperature melting the method of preparation , the process parameters of the preparation process . Its structure by XRD characterization, testing and research on the performance of the thermal properties of the glass viscosity , mechanical properties and chemical stability of the glass elements of its three main performance , determine the PDP substrates glass composition. Near the best composition of the PDP in the electrical and optical properties of the substrate glass test discussed PDP its compliance with the requirements of the substrate glass , glass substrate for large-scale production of the PDP provides some theoretical reference. A glass manufacturing process , at 1450 ℃ feed , the temperature was raised to 1480 ℃ melting 3. 5 h ( with a stirrer , stirring) , clarified at 1500 ℃ 0.75 hours , and incubated for 3 hours at 580 ℃ annealing . R2O-RO-Al2O3-ZrO2-SiO2 system , characterized by XRD of the samples for the glass phase, in accordance with the principles of the orthogonal test method , the glass sample thermal properties, mechanical properties and chemical stability , the results of the analysis results Showing: the order in which the primary and secondary each factor for thermal expansion coefficient, as follows: the alkali metal oxide GT ; ZrO2 GT ; of Al2O3 GT ; an alkaline earth metal oxide, GT ; of SiO2 ; for the transition temperature, the various factors of the order was : alkali metal oxide gt; ZrO2 gt; Al2O3 gt; SiO2 gt; alkaline earth metal oxide ; density , the order in which the primary and secondary factors : alkaline earth metal oxide gt ; ZrO2 gt ; SiO2 gt ; alkali metal oxide gt ; Al2O3 ; mechanical properties the order in which the primary and secondary factors : alkali metal oxide gt ; Al2O3 gt ; SiO2 gt ; ZrO2 gt ; alkaline earth metal oxide ; chemical stability , the primary and secondary order of various factors : the alkaline earth metal oxide gt ; SiO2 gt ; alkali metal oxides gt; Al2O3 gt; ZrO2. PDP substrate glass , the optimal composition of SiO2 55% , 3 % Al2O39 MgO 3. 8 % , CaO, 2 % , SrO, 7 % , 7% BaO , of Na2O 3. 2 % , K2O 5 2 1 of ZrO2 . 3%, TiO2 0. 3%, Sb2O3 0. 3%. The best composition of the PDP with a coefficient of thermal expansion of the substrate glass 80. 9 × 10-7
