   Günümüzde malzeme bilimi çok gelişmiş olmasına
rağmen, yeni teknolojik gereksinimler, var olanlardan farklı yeni nesil
malzemelere ihtiyaç duyulmaktadır. Yakın bir gelecekte uzay yolculuğunun
gerçekleşebilir olması; aşırı yüksek sıcaklık ortamlarında, çok amaçlı ve
tekrarlı kullanılabilir seramik kompozit malzemelerin geliştirilmesine bağlıdır.
Aşırı yüksek sıcaklık seramik malzemeleri (AYSS veya Ultra high temperature
ceramics-UHTC) 2300˚C ve üzerindeki ortamlarda kullanılabilir seramikler olarak
tanımlanmaktadır. Bu çalışmada, yüksek ergime noktasına sahip, kimyasal ve
termal kararlılığı olan AYSS grubuna ait,
ZrB2-ZrC-
SiC-Al
2O3
seramik kompozit tozlarının
üretimi, laboratuvar şartlarında, zirkon, borik asit, metalik alüminyum ve
grafit başlangıç karışımı kullanılarak araştırılmıştır. Alüminotermik yöntem
kullanılmış, başlangıç karışımları ve elde edilen reaksiyon ürünleri SEM, XRD,
XRF, TG/DTA gibi analiz yöntemleri ile analiz edilmiştir. Deneysel şartlara
bağlı olarak, başlangıç karışımında bulunan zirkon, çok düşük sıcaklıklarda
ayrışmıştır. Zirkonyum ve silisyum oksitleri, ZrC ve ZrB
2 ve SiC
fazına dönüştüğü görülmüştür. Karbür ve borür fazlarının haricinde, proses
edilmiş numunelerde Al
2O3 oluşumu da tespit edilmiştir.

      Although
material science is advanced at present time, new technological developments
require new generation and different materials that are commercially not
available in global market. In order to make long distance space journeys
possible in near future, innovation of multipurpose and reusable ceramic
composite materials for at high temperature environments are needed. Ceramics
that are useable at elevated temperatures as high as 2300˚C are called Ultra high
temperature ceramics (UHTC).
In this study,
the processing of UHTCs based on ZrC/ZrB
2/SiC/Al2O3
ceramic composite that has high melting point, chemical and thermal stability, at
the laboratory conditions was investigated using zircon, boric acid, carbon and
aluminium powders. Aluminothermic method was chosen, the starting mixtures and
the obtained reaction products were analysed using SEM, XRD, XRF and TG/DTA analysis
methods.
The experimental results showed that, the obtained sample
consists of ZrB
2/ZrC as a matrix phases.
