The suspension of hydrous colloidal zirconia particles (CZPs) was prepared from zirconium oxychloride solutions via thermal hydrolysis at acidic condition and at boiling point of 110 ºC for 72 h. Characterization of the obtained suspension and dried solid... see more

Characterization of the pillarization process product of ZrO2-montmorillonite from Zirconium oxychloride local made of PSTA-BATAN has been done. The objective of this research is to control the quality of pillarization process product of the new material ... see more

The design of chemical reactor can not be separated from the optimization data and reaction kinetics obtained from the experimental measurement. Through the idea of making the dissolution reactor design, the purpose of this research is to obtain optimizat... see more

ABSTRAKKeberadaan zirkon (ZrSiO4) di alam kebanyakan berasosiasi dengan beberapa senyawa oksida berharga (SOB) seperti TiO2 dan oksida logam tanah jarang atau rare earth oxides (REO). Keterdapatan mineral alam di Indonesia yang mengandung zirkonium (Zr) d... see more

Zirconia (ZrO2), an inorganic material, is a very fascinating material due to its high mechanical strength and fracture toughness. The synthesis is carried out by using the co-precipitation method using optimum content of zirconium oxychloride octahydrate... see more

Propolis is a natural product with very important properties and its chemical composition was investigated by many researchers. In the present study the polyphenols and flavonoid content was investigated for 10 Romanian propolis samples. Extracts were obt... see more

. Palynological analysis, total polyphenols, total flavonoids and antioxidant activity were studied on six samples fresh bee pollen from Transylvania. Floral origin of used bee collected pollen was identified by palynological analysis without acetolysis f... see more

Zirkonium merupakan bahan yang baik untuk dimanfaatkan dalam industri nuklir maupun industri non nuklir.Dalam industri nuklir, zirkonium adalah bahan yang strategis karena mempunyai tampang lintang absorpsi netron rendah. Tujuan penelitian ini adalah untu... see more

The present study deals with the synthesis and characterization of ZrO2 nanomaterial which can be used as an adsorbent for Molybdenum-99 (99Mo). The adsorbent can potentially be utilized as the material for 99Mo/99mTc generator column. Using the sol-gel m... see more
