CERAMIC SLURRIES WITH PHOTOREACTIVE-PHOTOSTABLE HYBRID BINDERS
Ceramic slurries may include ceramic particles, a photoreactive-photostable hybrid binder, and a photoinitiator. The photoreactive-photostable hybrid binder may include a photoreactive organic resin component, and one or more photostable siloxane components. Methods of forming a ceramic part may include curing a portion of a ceramic slurry by exposing the portion of the ceramic slurry to light to form a green ceramic part, and partially firing the green ceramic part to form a brown ceramic part. The brown ceramic part may be sintered at or above a sintering temperature of the ceramic particles to form a ceramic part, wherein sintering includes heating the brown ceramic part to a sufficient temperature to promote reaction bonding that converts silica from the photoreactive-photostable hybrid binder into silicates that bond with the ceramic particles.
陶瓷浆料可包含陶瓷颗粒、光反应性‑光稳定性混合粘结剂和光引发剂。光反应性‑光稳定性混合粘结剂可包含光反应性有机树脂组分和一种或多种光稳定性硅氧烷组分。形成陶瓷件的方法可包括通过将陶瓷浆料的一部分暴露于光来固化该部分陶瓷浆料以形成生坯陶瓷件，和部分烧制生坯陶瓷件以形成棕坯陶瓷件。可在陶瓷颗粒的烧结温度或更高的温度下烧结棕坯陶瓷件以形成陶瓷件，其中烧结包括加热棕坯陶瓷件至足够的温度以促进反应结合，该反应结合将来自光反应性‑光稳定性混合粘结剂的二氧化硅转化为与陶瓷颗粒结合的硅酸盐。
