AMORF BOR KATKILI DUVAR KAROSU SERAMİKLERİNİN ÜRETİMİ VE KARAKTERİZASYONU

Abstract

Bu çalışma, amorf borun (Fluka Boron) seramik duvar karolarının mekanik ve termal özellikleri üzerindeki etkilerini araştırmaktadır. Bor konsantrasyonları %0, %1, %3, %5, %7 ve %9 olan numuneler 1000°C'de sinterlenmiştir. Sonuçlar, orta düzeyde amorf bor ilavelerinin (%3-%5), artan yoğunlaşma ve azalan gözeneklilik nedeniyle yığın yoğunluğunu ve basınç dayanımını önemli ölçüde artırdığını göstermiştir. Bu etkiler, borun sinterleme sırasında partikül bağlanmasını teşvik eden akışkanlaştırma etkisine bağlanmaktadır. %5'e kadar amorf bor ilavelerinin mekanik özellikleri ve termal iletkenliği artırdığı ve bu konsantrasyonda optimum performans gösterdiği görülmüştür. Bununla birlikte, %5'i aşan amorf bor seviyeleri, görünür gözenekliliğin azalmasına rağmen camsı faz oluşumu ve yapısal heterojenlik nedeniyle mekanik mukavemet ve termal iletkenliğin azalmasına yol açmıştır. Duvar karosu seramikleri üzerine yapılan bu çalışma, basınç dayanımı ve termal iletkenlik performansını artırmak için yoğunlaştırma, faz bileşimi ve mikro yapıyı dengelemede amorf bor konsantrasyonunun kritik rolünü vurgulamaktadır. Bor içeriği ve malzeme performansı arasındaki etkileşimi vurgulayarak, araştırma sürdürülebilir, yüksek performanslı seramik malzemelerin geliştirilmesine yönelik değerli bilgilere katkıda bulunmaktadır.

PRODUCTION AND CHARACTERIZATION OF WALL TILE CERAMICS WITH THE ADDITION OF AMORPHOUS BORON

Abstract

This study investigates the effects of amorphous boron (Fluka Boron) on the mechanical and thermal properties of ceramic wall tiles. Samples with boron concentrations of 0%, 1%, 3%, 5%, 7%, and 9% were sintered at 1000°C. Results showed that moderate amorphous boron additions (3%–5%) significantly improved bulk density and compressive strength due to enhanced densification and reduced porosity. These effects are attributed to boron's fluxing action, which promotes particle bonding during sintering. Amorphous boron additions of up to 5% were observed to enhance mechanical properties and thermal conductivity, with optimal performance at this concentration. However, amorphous boron levels exceeding 5% led to diminished mechanical strength and thermal conductivity due to the formation of a glassy phase and structural heterogeneity, despite reduced apparent porosity. This study on wall tile ceramics highlights the critical role of amorphous boron concentration in balancing densification, phase composition, and microstructure to enhance compressive strength and thermal conductivity performance. By highlighting the interplay between boron content and material performance, the research contributes valuable knowledge toward the development of sustainable, high-performance ceramic materials.
