The study deals with production of the glass-ceramics
from natural raw material vermiculite. The machinability properties of the glass-ceramic
compositions were investigated depending on vermiculite and MgF2
contents. The compositions containing 80 %, 85 %, 90 % vermiculite, 5 % K2O
and MgF2 as remainder were mixed by using a ball mill for 2 h and
coded as VER80, VER85 and VER90. The mixed and milled powders were sieved and
disc samples were prepared by pressing at 100 MPa. The shaped samples were
sintered at 900-1100 ºC for 1 h. X-ray diffraction (XRD), scanning electron
microscopy (SEM), and machinability test were conducted. The results have indicated
that the samples have good sintering and machinability properties.

 Bu
çalışmada doğal hammadde olan Vermikülitten cam-seramik malzemeler
üretilmiştir. Çalışmada; Vermikülit ve MgF
2 oranına bağlı olarak
işlenebilirlik özelliklerindeki değişimler araştırılmıştır.
  VER80, VER85 ve VER90 şeklinde kodlanan üç
ayrı bileşimde K
2O oranı %5 olarak sabit tutulmuş, MgF2
ve Vermikülit oranları karşılıklı değiştirilmiştir. Bileşimler bilyeli değirmende
2 saat süre ile karıştırılmıştır. Karıştırma sonrası tozlar elenmiş ve 100 MPa
yük altında tek eksenli basma cihazı ile şekillendirilmiştir. Preslenen
numuneler 900-1100 °C sıcaklıklarda 1 saat süre ile sinterlenmiştir.
Sinterlenen numuneler X-ışını difraksiyon analizi (XRD),
  taramalı elektron mikroskobu (SEM) ve
işlenebilirlik testleri ile karakterize edilmiştir. Sonuçlar üretilen
numunelerin iyi işlenebilirlik özellikleri taşıdığını göstermektedir.
