Two-step sintering (TSS) uses two different sintering temperatures. The first sintering temperature should guarantee a relative density higher than 75% of theoretical sample density. This will remove supercritical pores from the body. The sample will then be cooled down and held at the second sintering temperature until densification is completed.
Tammann temperature was pioneered by German astronomer, solid-state chemistry, and physics professor Gustav Tammann in the first half of the 20th century. [1]: 152 He had considered a lattice motion very important for the reactivity of matter and quantified his theory by calculating a ratio of the given material temperatures at solid-liquid phases at absolute temperatures.

Some recipes call for a 450°F oven, but I find it best to kick the temperature down a notch and roast at 425°F. It takes a little bit more time to get the vegetables brown and crispy—and of ...

Understanding the role of temperature in cooking is an essential part of creating fine cuisine. Temperature plays a vital role in nearly every meal's preparation. Many aspects of cooking rely on the proper treatment of colloids. Things such as sauces, soups, custards, and butters are all created by either creating or destroying a colloid.
Carryover cooking (sometimes referred to as resting) is when foods are halted from actively cooking and allowed to equilibrate under their own retained heat.Because foods such as meats are typically measured for cooking temperature near the center of mass, stopping cooking at a given central temperature means that the outer layers of the food will be at higher temperature than that measured.
Liquid phase sintering is a sintering technique that uses a liquid phase to accelerate the interparticle bonding of the solid phase. In addition to rapid initial particle rearrangement due to capillary forces, mass transport through liquid is generally orders of magnitude faster than through solid, enhancing the diffusional mechanisms that drive densification.
