A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)
Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ...
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
(Elsevier Sci LTD, 2009)
alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ...
A comparison of sintering techniques using different particle sized beta-SiAlON powders
(Elsevier Sci LTD, 2012)
In the present study sintering behavior and mechanical properties of beta-SiAlON ceramics were investigated using different sintering techniques (gas pressured sintering (GPS), pressureless sintering and spark plasma ...
The effect of the wet-milling process on sintering temperature and the amount of additive of SiAlON ceramics
(Elsevier Sci LTD, 2010)
In this study, nano-sized SiAlON powders were produced by wet milling at elevated speeds as a top-to-bottom process. Before the milling process, different milling times and mediums were performed for the determination of ...
The effects of processing on the alpha <-> beta SiAlON transformation during cycling heat treatments
(Elsevier Science Sa, 2008)
Typical alpha/beta-SiAlON starting composition of formula Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38) was densified by two different sintering processes, hot pressing (HP) and gas pressure sintering (GPS), using Nd(2)O(3) as ...
Tailoring the properties of spark plasma sintered SiAlON containing graphene nanoplatelets by using different exfoliation and size reduction techniques: Anisotropic mechanical and thermal properties
(Elsevier Sci LTD, 2018)
SiAlON ceramics are intensively used in different areas but still there is a need to improve the mechanical and thermal properties as well as ease of machinability and reduce the weight. In this study, the effect of graphene ...
